On sm8450 platform the CTL_0 doesn't differ from the rest of CTL blocks,
so switch it to CTL_SC7280_MASK too.

Some background: original commit 100d7ef6995d ("drm/msm/dpu: add support
for SM8450") had all (relevant at that time) bit spelled individually.
Then commit 0e91bcbb0016 ("drm/msm/dpu: Add SM8350 to hw catalog"),
despite being a mismerge, correctly changed all other CTL entries to use
CTL_SC7280_MASK, except CTL_0.

While the current BLOCK_SOC_MASK style is not ideal (and while we are
working on a better scheme), let's follow its usage as a least minimal
surprise. For example, sc8280xp, a close associate of sm8450, also uses
CTL_SC7280_MASK.

Although I dont totally agree with this, but because sc8280xp also uses the same, I am fine.

But either we need to work on a better scheme or expand the macros but not duplicate these for the next chipset which gets added.
