uart: pass register width in the coreboot table
Some SOCs (like pistachio, for instance) provide an 8250 compatible UART, which has the same register layout, but mapped to a bus of a different width.
Instead of adding a new driver for these controllers, it is better to have coreboot report UART register width to libpayload, and have it adjust the offsets accordingly when accessing the UART.
