Hi ARM SoC Team,

Please pull !

We pushed several extra conformance checks in the SCMI driver and quite a few
firmware bugs have been discovered with that. Due to absence of formal
conformace test suite for SCMI, we have to workaround them in the kernel for
now :(.

Regards,
Sudeep

Arm SCMI firmware driver fixes for v5.19

Few more fixes to address:
1. Issue reported on Juno with HDLCD clock which turned out to be yet
   another firmware issue. The firmware is not conformant to the spec and
   we now have to workaround as this may be copied to other platforms as
   well. The spec expects to return size of 3 for a range clock rate
   description while the firmware returns 1. We have other ways to validate
   all the 3 entries the driver reads are polpulated and we use the same
   to workaround this firmware bug.

2. Optee transport not setting the correct reponse length which is similar
   to the one reported earlier on Rockchip platform.

3. Drop the usage of the deprecated ida_simple_{get,remove} and migrate to the
   ida_{alloc,free}
