soc/intel/{skl,cnl,xsp,icl,tgl,ehl,adl,jsl}: use common LPC mirroring
Drop the old, redundant code for mirroring LPC registers to DMI and make
use of the new common code.
Select the new Kconfig option for LPC DMI mirroring by the option
SOC_INTEL_COMMON_PCH_BASE, which is selected by platforms starting with
SPT, except APL and Xeon-SP. For Xeon-SP, select DMI and the new Kconfig
directly.
APL, even though it's younger than SPT, does not need mirroring.
Test: Set LGMR address by calling `lpc_open_mmio_window` and check that
both the PCI cfg and DMI LGMR register get written correctly.
Tested successfully on clevo/cml-u.
