[PATCH v] drm/amd/pm: Enable VCN reset for pgm=4 with appropriate FW version

[PATCH v] drm/amd/pm: Enable VCN reset for pgm=4 with appropriate FW version

[Jesse.Zhang]

Extend the VCN reset capability to include pgm=4 variants when the
firmware version meets the required threshold (>= 0x04557100). This
follows the existing pattern for pgm=0 and pgm=7, ensuring that VCN
reset is enabled only on configurations where it is supported by the
firmware.
