Check for errors from bus_generic_detach in various drivers

In some cases, move the call to bus_generic_detach earlier so that any
detach failures from child devices do not leave the parent device
partially detached.

Move Ti AM335x to dev/extres/clk framework.

Re-implement clocks for these SoC by using now standard extres/clk framework.
This is necessary for future expansion of these. The new implementation
is (due to the size of the patch) only the initial (minimum) version.
It will be updated/expanded with a subsequent set of particular patches.

This patch is also not tested on OMAP4 based boards (BeagleBone),
so all possible issues should be (and will be) fixed by ASAP once
identified.

Support the SPI mode and bus clock frequency parameters set by the devices
requesting SPI transfers.

Reported by: SAITOU Toshihide <toshi@ruby.ocn.ne.jp>

ofw_spi: Parse property for the SPI mode and CS polarity.
As cs is stored in a uint32_t, use the last bit to store the
active high flag as it's unlikely that we will have that much CS.

Bump up the read and write timeouts. The old value was too small for low

Add the SPI driver for am335x.

This driver works in PIO mode for now, interrupts are available only when
FIFO is enabled. The FIFO cannot be used with arbitrary sizes which defeat
its general use.

Add the SPI driver for am335x.

This driver works in PIO mode for now, interrupts are available only when
FIFO is enabled. The FIFO cannot be used with arbitrary sizes which defeat
its general use.

At some point we can add DMA transfers where the FIFO can be more useful.

Tested on uBMC (microBMC) and BBB.
