6037400b5a It's probably time I learn C.
Fix a few while (!uart_getreg() & SR1_TNF) when
while (!(uart_getreg() & SR18TNF)) was really meant.
This driver should die anyway, it's awful, and uart_ns8250 should be fine
for the StrongArm 1110. I'll kill it later.

f8100ce2a7 Don't expose the uart_ops structure directly, but instead have
it obtained through the uart_class structure. This allows us
to declare the uart_class structure as weak and as such allows
us to reference it even when it's not compiled-in.
It also allows is to get the uart_ops structure by name, which
makes it possible to implement the dt tag handling in uart_getenv().
The side-effect of all this is that we're using the uart_class
structure more consistently which means that we now also have
access to the size of the bus space block needed by the hardware
when we map the bus space, eliminating any hardcoding.

97202af2dc - Add a uart_rxready() and corresponding device-specific implementations
that can be used to check whether receive data is ready, i.e. whether
  the subsequent call of uart_poll() should return a char, and unlike
  uart_poll() doesn't actually receive data.
- Remove the device-specific implementations of uart_poll() and implement
  uart_poll() in terms of uart_getc() and the newly added uart_rxready()
  in order to minimize code duplication.
- In sunkbd(4) take advantage of uart_rxready() and use it to implement
  the polled mode part of sunkbd_check() so we don't need to buffer a
  potentially read char in the softc.
- Fix some mis-indentation in sunkbd_read_char().

c1bfc47fa7 Now that we use pmap_mapdev_boostrap(), we can get ride of the got_mmu
hack.

9c8c02e7a0 Use macros instead of hardcoding the address for SACOM1. Also don't
pretend we're working with SACOM3, as we're really mapping SACOM1.
