[Koba Ko]

BugLink: https://bugs.launchpad.net/bugs/1932993

[Impact]
AMD introduce a new firmware and has been SRUed in this public bug.
https://bugs.launchpad.net/ubuntu/focal/+source/linux-firmware/+bug/1929147

For the kernel(oem-5.10/groovy), also need other patches to load this firmware.

[Fix]
Support to load polaris12_32_mc.bin

[Test]
1. Check by modinfo and cnofirm polaris12_32_mc.bin is loaded by amdgpu.ko

#modinfo amdgpu | grep polaris12_32_mc.bin
firmware: amdgpu/polaris12_32_mc.bin

2. Equipped the rx540(PD5001) that would trigger issue and system would bootup successfully into desktop.
*some rx540(PD5000) can't trigger the issue.

[Regression Potential]
Medium, introduce a brand new firmware may cause regression.
