Alistair Francis 450aaae863 cadence_uart: Check baud rate generator and divider values on migration 
The Cadence UART device emulator calculates speed by dividing the
baud rate by a 'baud rate generator' & 'baud rate divider' value.
The device specification defines these register values to be
non-zero and within certain limits. Checks were recently added when
writing to these registers but not when restoring from migration.

This patch adds checks when restoring from migration to avoid divide by
zero errors.
