drm/i915: Make RING_PDP relative to engine->mmio_base
The PDP registers are an oddity inside the set of context saved
registers in that they take the engine as a parameter to the macro and
not the mmio_base as the others do. Make it accept the engine->mmio_base
for consistency in programming the context registers.
add/remove: 0/0 grow/shrink: 2/1 up/down: 3/-32 (-29)
Function old new delta
emit_ppgtt_update 324 326 +2
capture 5102 5103 +1
execlists_init_reg_state.isra 1128 1096 -32
And similar savings later!
