Peter Maydell 935fe442dc hw/intc/armv7m_nvic: Allow byte accesses to SHPR1
The code for handling the NVIC SHPR1 register intends to permit
byte and halfword accesses (as the architecture requires). However
the 'case' line for it only lists the base address of the
register, so attempts to access bytes other than the first one
end up in the "bad write" default logic. This bug was added
accidentally when we split out the SHPR1 logic from SHPR2 and
SHPR3 to support v6M.

Fixes: 7c9140afd5 ("nvic: Handle ARMv6-M SCS reserved registers")

The Zephyr RTOS happens to access SHPR1 byte at a time,
which is how I spotted this.
