Joe Komlodi 4a71d6d32e hw/registerfields: Add shared fields macros 
Occasionally a peripheral will have different operating modes, where the
MMIO layout changes, but some of the register fields have the same offsets
and behaviors.

To help support this, we add SHARED_FIELD_XX macros that create SHIFT,
LENGTH, and MASK macros for the fields that are shared across registers,
and accessors for these fields.

An example use may look as follows:
There is a peripheral with registers REG_MODE1 and REG_MODE2 at
different addreses, and both have a field FIELD1 initialized by
SHARED_FIELD().

Depending on what mode the peripheral is operating in, the user could
extract FIELD1 via
SHARED_ARRAY_FIELD_EX32(s->regs, R_REG_MODE1, FIELD1)
or
SHARED_ARRAY_FIELD_EX32(s->regs, R_REG_MODE2, FIELD1)
