VCN shared memory is in framebuffer and there are some flags initialized
during sw_init. Ideally, such programming should be during hw_init.
Make sure the flags are saved during reset on initialization since that
reset will affect frame buffer region. For clarity, separate it out to
another function.

The VCN firmware loading path enables the indirect SRAM mode if it's
advertised as supported. We might have some cases of FW issues that
prevents this mode to working properly though, ending-up in a failed
probe. An example below, observed in the Steam Deck:
[...]
[drm] failed to load ucode VCN0_RAM(0x3A)
[drm] psp gfx command LOAD_IP_FW(0x6) failed and response status is (0xFFFF0000)
amdgpu 0000:04:00.0: [drm:amdgpu_ring_test_helper [amdgpu]] *ERROR* ring vcn_dec_0 test failed (-110)
[drm:amdgpu_device_init.cold [amdgpu]] *ERROR* hw_init of IP block <vcn_v3_0> failed -110
amdgpu 0000:04:00.0: amdgpu: amdgpu_device_ip_init failed
amdgpu 0000:04:00.0: amdgpu: Fatal error during GPU init
[...]
Disabling the VCN block circumvents this, but it's a very invasive
workaround that turns off the entire feature. So, let's add a quirk
on VCN loading that checks for known problematic BIOSes on Vangogh,
so we can proactively disable the indirect SRAM mode and allow the
HW proper probe and VCN IP block to work fine.
