Check definition of uart status register

[mdhayter]

Verilator gives a warning:
%Warning-UNUSED: ../src/lowrisc_ip_uart_0.1/rtl/uart_core.sv:12: Bits of signal are not used: reg2hw[99:88]

This corresponds to the q and re bits for the status register. Should the register be declared hwo and not have hwre set? (I think at one point there were some read side-effects)

@eunchan
do you mind taking a look? Just wondering if this falls under the things we should clean up for uart hero.

@weicaiyang FYI

This looks like waived in the lint and it is OK as it is now. A few of the fields in the register are used in the design
