[PATCH v3 1/5] xen: rename ns16550-uart.h to 8250-uart.h and fix some typos

[Chen Baozi <baozich@gmail.com>]

Since UARTs on OMAP5 & Allwinner's SoC are not ns16550 but only 8250
compatible, rename ns16550-uart.h to 8250-uart.h, which is a more pervasive
name. At the same time, fix some typos, which have redundance UART_
prefixes in some macros.
