media: synopsys: csi2rx: add i.MX93 support
The i.MX93 uses a newer version of the DW CSI-2 controller with a changed
register layout and an integrated Image Pixel Interface (IPI), which
converts the received CSI-2 packets from byte to pixel format and produces
a pixel data bus containing vertical and horizontal synchronization
information.
The reset flow also differs, so add the .assert_reset(), .deassert_reset(),
and .idi_enable() callbacks to support it.

media: synopsys: csi2rx: Use enum and u32 array for register offsets
Use enum dw_mipi_csi2rx_regs_index together with a u32 array to describe
register offsets. This allows supporting new IP versions with different
register layouts in a structured way.
Add rk3568_regs matching the previous macro definitions and pass it as
driver data during probe.
No functional change intended.

Only check for error returns (< 0) to support more SoCs.

hdmirx_dev->num_cks variable needs to be signed for the error handling to
work.

bt->pixelclock is __u64, which causes the compiler to emit a libcall for

this.
