[PATCH/RFC 5/8] serial: pxa: Make the driver buildable for BCM7xxx set-top platforms

[Kevin Cernekee <cernekee@gmail.com>]

Remove the platform dependency in Kconfig and add an appropriate
compatible string.  Note that BCM7401 has one 16550A-compatible UART
in the UPG uart_clk domain, and two proprietary UARTs in the 27 MHz
clock domain.  This driver handles the former one.
