soc: aspeed: Add UART routing support 
Add driver support for the UART routing control. Users can perform
runtime configuration of the RX muxes among the UART controllers and
the UART IO pins.

The sysfs interface is also exported for the convenience of routing paths
check and update.

config ASPEED_LPC_CTRL tristate "ASPEED LPC firmware cycle control" select REGMAP select MFD_SYSCON default ARCH_ASPEED help Control LPC firmware cycle mappings through ioctl()s. The driver also provides a read/write interface to a BMC ram region where the host LPC read/write region can be buffered.

config ASPEED_LPC_SNOOP tristate "ASPEED LPC snoop support" select REGMAP select MFD_SYSCON default ARCH_ASPEED help Provides a driver to control the LPC snoop interface which allows the BMC to listen on and save the data written by the host to an arbitrary LPC I/O port.

config ASPEED_UART_ROUTING tristate "ASPEED uart routing control" select REGMAP select MFD_SYSCON default ARCH_ASPEED help Provides a driver to control the UART routing paths, allowing users to perform runtime configuration of the RX muxes among the UART controllers and I/O pins.

config ASPEED_P2A_CTRL tristate "ASPEED P2A (VGA MMIO to BMC) bridge control" select REGMAP select MFD_SYSCON default ARCH_ASPEED help Control ASPEED P2A VGA MMIO to BMC mappings through ioctl()s. The driver also provides an interface for userspace mappings to a pre-defined region.

config ASPEED_SOCINFO bool "ASPEED SoC Information driver" default ARCH_ASPEED select SOC_BUS default ARCH_ASPEED help Say yes to support decoding of ASPEED BMC information.
