Peter Maydell d33abe82c7 target/arm: Implement dummy versions of M-profile FP-related registers 
The M-profile floating point support has three associated config
registers: FPCAR, FPCCR and FPDSCR. It also makes the registers
CPACR and NSACR have behaviour other than reads-as-zero.
Add support for all of these as simple reads-as-written registers.
We will hook up actual functionality later.

The main complexity here is handling the FPCCR register, which
has a mix of banked and unbanked bits.

Note that we don't share storage with the A-profile
cpu->cp15.nsacr and cpu->cp15.cpacr_el1, though the behaviour
is quite similar, for two reasons:
 * the M profile CPACR is banked between security states
 * it preserves the invariant that M profile uses no state
   inside the cp15 substruct
