This reverts commit 34a33d4683cba7ba63c894132efb1998c0217631.
34a33d4683cba7ba63c894132efb1998c0217631 was a driver workaround
when PSP firmware was not ready. Now the PSP fw is ready so we
revert this driver workaround.

Add one function to calculate BO's GPU physical address.
And another function to calculate BO's CPU physical address.
v2: Use functions vs macros (Christian)
Use more proper function names (Christian)

Add one function to calculate BO's GPU physical address.
And another function to calculate BO's CPU physical address.
v2: Use functions vs macros (Christian)
Use more proper function names (Christian)
