Allow down to 8-bit access, per the datasheet (reference added
in previous commit):
"Timer Counter registers are accessed as one of the following types:
• Byte (8 bits)
• Half word (2 bytes)
• Word (4 bytes)"

RFC: This breaks the UART qtest, instead of having TX register
receiving 'T' = 0x54, it receives 0x54000000, converted to '\0'
char. It works if we use SWI instead of SBI (storing 32-bit).
