mips: select legacy gpiolib interfaces where used

A few old machines have not been converted away from the old-style
gpiolib interfaces. Make these select the new CONFIG_GPIOLIB_LEGACY
symbol so the code still works where it is needed but can be left
out otherwise.

This is the list of all gpio_request() calls in mips:

arch/mips/alchemy/devboards/db1000.c: gpio_request(19, "sd0_cd");
arch/mips/alchemy/devboards/db1000.c: gpio_request(20, "sd1_cd");
arch/mips/alchemy/devboards/db1200.c: gpio_request(215, "otg-vbus");
arch/mips/bcm47xx/workarounds.c: err = gpio_request_one(usb_power, GPIOF_OUT_INIT_HIGH, "usb_power");
arch/mips/bcm63xx/boards/board_bcm963xx.c: gpio_request_one(board.ephy_reset_gpio,
arch/mips/txx9/rbtx4927/setup.c: gpio_request(15, "sio-dtr");

Most of these should be easy enough to change to modern gpio descriptors
or remove if they are no longer in use.

MIPS: VDSO: Fold MIPS_CLOCK_VSYSCALL into MIPS_GENERIC_GETTIMEOFDAY

This configuration option exists so "that we don't provide the symbol
when there's no possibility of there being a usable clocksource".
However it only covers __vdso_gettimeofday() and none of the other vDSO
functions which should be affected by the same circumstances.slightly slightly.

Remove MIPS_CLOCK_VSYSCALL and fold its usecase into
MIPS_GENERIC_GETTIMEOFDAY, which works correctly.

MIPS: mobileye: Remove duplicate FIT_IMAGE_FDT_EPM5 from main Kconfig

kconfiglint reports:

K008: config FIT_IMAGE_FDT_EPM5 has prompts in 2 separate definitions

The FIT_IMAGE_FDT_EPM5 Kconfig symbol is defined identically in two places:

arch/mips/Kconfig:1052
arch/mips/mobileye/Kconfig:17

Both have the same prompt, depends, default, and help text. Since
arch/mips/mobileye/Kconfig is sourced from arch/mips/Kconfig, both
definitions are parsed and the symbol ends up with two prompts.

The symbol was first introduced in commit 101bd58fde10 ("MIPS: Add
support for Mobileye EyeQ5") directly in
arch/mips/Kconfig. Three months later, commit fbe0fae601b7 ("MIPS:
mobileye: Add EyeQ6H support") created the
arch/mips/mobileye/Kconfig sub-file to organize the growing Mobileye
platform code and added the MACH_EYEQ5/MACH_EYEQ6H choice along with
a copy of FIT_IMAGE_FDT_EPM5. However, the original definition in
arch/mips/Kconfig was not removed at that time, leaving a duplicate.

Remove the definition from arch/mips/Kconfig, keeping the one in
arch/mips/mobileye/Kconfig where it belongs alongside the related
MACH_EYEQ5 machine type definition that it depends on.

MIPS: Implement ARCH_HAS_CC_CAN_LINK

The generic CC_CAN_LINK detection does not handle different byte orders
or ABIs. This may lead to userprogs which are not actually runnable on
the target kernel.

Use architecture-specific logic supporting byte orders instead.

Modern 64-bit toolchains default to a n32 libc, which are not
supported by all kernel configurations, as MIPS32_N32 is optional.
On 64-bit, test for a n32 ABI libc first and fall back to o64 and
o32 if necessary.

sched: Unify the SCHED_{SMT,CLUSTER,MC} Kconfig

Like many Kconfig symbols, SCHED_{SMT,CLUSTER,MC} are duplicated
across arch/*/Kconfig. Try and clean up a little.

MIPS: loongson32: Switch to generic core

The generic MIPS core is fully compatible with Loongson-1 SoCs,
so migrate Loongson-1 to it.

Main changes are:
- Merge CPU_LOONGSON1B and CPU_LOONGSON1C into a unified CPU_LOONGSON32,
as both are based on the GS232 core.
- Consolidate LOONGSON1_LS1B and LOONGSON1_LS1C Kconfig options into
MACH_LOONGSON32.
- Enable MACH_GENERIC_CORE and remove the legacy custom implementation.
- Remove all Loongson-1 platform devices and associated code,
which are now obsolete due to Device Tree support.
- Misc cleanup.

Partially based on earlier work by Jiaxun Yang.

mips: Unconditionally select ARCH_HAS_CURRENT_STACK_POINTER

Now that the minimum supported version of LLVM for building the kernel
has been bumped to 15.0.0, the selection of
ARCH_HAS_CURRENT_STACK_POINTER can be made unconditional since it is
always true.
