UART 8250: Unconditionally provide register constants and use UART8250 prefix.

Browse source 
The register indexes and bitfield masks were guarded by the UART8250 config
options, but it might be (is) necessary to use them in a driver that is
UART8250 like without actually using the 8250 driver itself. To avoid any name
collision with other drivers, also change the constant prefix from UART_ to
UART8250_.

BUG=None
TEST=Built for link, lumpy, pit, and nyan. With this and other changes, got
bootblock serial output on nyan.
BRANCH=None
