[PATCH v2 2/7] clk: en7523: remove REG_PCIE*_{MEM,MEM_MASK} configuration

[Lorenzo Bianconi <lorenzo@kernel.org>]

REG_PCIE*_MEM and REG_PCIE*_MEM_MASK regs (PBUS_CSR memory region) are not
part of the scu block on the EN7581 SoC and they are used to select the
PCIE ports on the PBUS, so remove this configuration from the clock driver
and set these registers in the PCIE host driver instead.
This patch does not introduce any backward incompatibility since the dts
for EN7581 SoC is not upstream yet.
