tty/8250_dw: Add support for OCTEON UARTS.
A few differences needed by OCTEON:
o These are DWC UARTS, but have USR at a different offset.
o Internal SoC buses require reading back from registers to maintain
write ordering.
o 8250 on OCTEON appears with 64-bit wide registers, so when using
readb/writeb in big endian mode we have to adjust the membase to hit
the proper part of the register.
o No UCV register, so we hard code some properties.
Because OCTEON doesn't have a UCV register, I change where
dw8250_setup_port(), which reads the UCV, is called by pushing it in
to the OF and ACPI probe functions, and move unchanged
dw8250_setup_port() earlier in the file.
