i3c: ast2600: enable IBI support
The ast2600 i3c hardware is capable of IBIs, but we need a workaround for a hardware issue with the I3C state machine handling IBI payloads of specific lengths when PEC is not enabled. To avoid this, we need to unconditionally enable PECs, at the consquence of losing a byte of data when the device does not send a PEC. Enable IBIs on the ast2600 platform, including an implementation of the PEC workaround, which prints a warning when triggered. Signed-off-by:Jeremy Kerr <jk@codeconstruct.com.au> Reviewed-by:
