soc/intel/common: Enable decoding of the COMB range to LPC based on Kconfig
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.
