qcom: vpu: fix SC7280 VPU Gen2 firmware and add compatibility symlink

Browse source 
The earlier upstreamed firmware (vpu20_p1_gen2) for the SC7280 VPU was
incorrectly signed with an MBNv7 header. SC7280 only supports firmware
with an MBNv6 header, but this requirement was not communicated by the
developer who had validated the binary, leading to an incompatible
firmware being published to linux-firmware.

This change adds the correct and properly tested firmware image
vpu20_p1_gen2_s6.mbn, which is signed with an MBNv6 header and works on
SC7280 hardware.

Since some existing code references the older firmware name
vpu20_p1_gen2, add a compatibility link in WHENCE to preserve backwards
compatibility.
