After a recent change in clang to expose uninitialized warnings from
const variables and pointers [1], there is a warning in
imu_v12_0_program_rlc_ram() because data is passed uninitialized to
program_imu_rlc_ram():
drivers/gpu/drm/amd/amdgpu/imu_v12_0.c:374:30: error: variable 'data' is uninitialized when used here [-Werror,-Wuninitialized]
374 | program_imu_rlc_ram(adev, data, (const u32)size);
| ^~~~
As this warning happens early in clang's frontend, it does not realize
that due to the assignment of r to -EINVAL, program_imu_rlc_ram() is
never actually called, and even if it were, data would not be
dereferenced because size is 0.
Just initialize data to NULL to silence the warning, as the commit that
added program_imu_rlc_ram() mentioned it would eventually be used over
the old method, at which point data can be properly initialized and
used.

Some of the firmware that is loaded by amdgpu is not actually required.
For example the ISP firmware on some SoCs is optional, and if it's not
present the ISP IP block just won't be initialized.
The firmware loader core however will show a warning when this happens
like this:
```
Direct firmware load for amdgpu/isp_4_1_0.bin failed with error -2
```
To avoid confusion for non-required firmware, adjust the amd-ucode helper
to take an extra argument indicating if the firmware is required or
optional.
On optional firmware use firmware_request_nowarn() instead of
request_firmware() to avoid the warnings.

This commit fixes potential truncation when writing the string _imu.bin
into the fw_name buffer in the imu_v12_0_init_microcode function in the
imu_v12_0.c file
The ucode_prefix size was reduced from 30 to 15 to ensure the snprintf
function does not exceed the size of the fw_name buffer.
Thus fixing the below with gcc W=1:
drivers/gpu/drm/amd/amdgpu/imu_v12_0.c: In function ‘imu_v12_0_init_microcode’:
drivers/gpu/drm/amd/amdgpu/imu_v12_0.c:51:54: warning: ‘_imu.bin’ directive output may be truncated writing 8 bytes into a region of size between 4 and 33 [-Wformat-truncation=]
51 | snprintf(fw_name, sizeof(fw_name), "amdgpu/%s_imu.bin", ucode_prefix);
| ^~~~~~~~
drivers/gpu/drm/amd/amdgpu/imu_v12_0.c:51:9: note: ‘snprintf’ output between 16 and 45 bytes into a destination of size 40
51 | snprintf(fw_name, sizeof(fw_name), "amdgpu/%s_imu.bin", ucode_prefix);

The old method (program_imu_rlc_ram_old) should be
