Well that's a mistake. Its uart uses 32-bit registers, and 8-bit
access is not documented to be acceptable.
Apologies for forgetting to at least compile-test this for all
affected targets, I really should have done that.

No, this was based on my knowledge that freon/primus SoCs
(OMAP-L1xx/AM1xxx/TMS320C674x/DA8xx) are architecturally members of
the TI C6x family and not remotely related to the OMAP (despite the
part code "OMAP-L1xx"), and I double-checked the technical reference
manual: their UART is identical to that on Keystone.
