Vadim Bendebury 6cc5e52ec6 libpayload: read register width from 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.

BRANCH=none
BUG=chrome-os-partner:31438
TEST=with the rest of the patches integrated depthcharge console messages
     show up when running on the FPGA board
