soc/intel: Drop casts around `soc_read_pmc_base()`
The `soc_read_pmc_base()` function returns an `uintptr_t`, which is then
casted to a pointer type for use with `read32()` and/or `write32()`. But
since commit b324df6a540d154cc9267c0398654f9142aae052 (arch/x86: Provide
readXp/writeXp helpers in arch/mmio.h), the `read32p()` and `write32p()`
functions live in `arch/mmio.h`. These functions use the `uintptr_t type
for the address parameter instead of a pointer type, and using them with
the `soc_read_pmc_base()` function allows dropping the casts to pointer.
