[DNM PATCH v1 7/7] reduced SpacemiT K3 vendor BSP: set uart compatible for mainline OpenSBI

[E Shattow <e@freeshell.de>]

From: E Shattow <eshattow@users.noreply.github.com>

Do Not Merge

Informational purpose only, to aid mainline development of SpacemiT K3
support.

"The compatible order makes OpenSBI select UART_CAP_UUE and preserve
UART_IER_UUE (bit 6); matching only 'ns16550' writes 0x00 to UART_IER and
stops serial output." from [1] OpenSBI mailing list series
"platform: generic: spacemit: add K3 platform support"
