Starting with SPT, LPC registers IOD, IOE, LGIR* and LGMR need to be
mirrored to their corresponding DMI registers. Add the required writes
to DMI registers, where the PCI config registers get written.
This is already done in soc code for IOD, IOE and LGIR* by mirroring
the registers later, during PCH init. Also the code mostly matches
accross the platforms. This common implementation will avoid delayed
mirroring of the registers and also deduplicate the code.
This change also adds a new Kconfig that will be selected by platforms
requiring mirroring of LPC IO/MMIO registers to their corresponding DMI
registers.
For making use of this common code, the redundant soc code needs to be
dropped and the newly introduced Kconfig option has to be selected. This
is done in the follow-up change.

By default all Intel platform has enable IO decode range for COMA if
CONFIG_DRIVERS_UART_8250IO is selected.
With this patch, COMB will get enable based on
CONFIG_SOC_INTEL_COMMON_BLOCK_LPC_COMB_ENABLE Kconfig selection.
Also make lpc_enable_fixed_io_ranges() function returns Enabled I/O bits to avoid
an additional pci configuration read to get the same data.

Add LPC common code to be shared across Intel platforms.
Also add LPC library functions to be shared across platforms.
Use common LPC code for Apollo Lake soc. Update existing Apollolake
mainboard variants {google,intel,siemens} to use new common
LPC header file.
