target-arm: Drop success/fail return from cpreg read and write functions

All cpreg read and write functions now return 0, so we can clean up
their prototypes: * write functions return void * read functions return the value rather than taking a pointer
to write the value to...

target-arm: Remove unnecessary code now read/write fns can't fail

Now that cpreg read and write functions can't fail and throw an
exception, we can remove the code from the translator that synchronises
the guest PC in case an exception is thrown.

target-arm: Convert generic timer reginfo to accessfn

Convert the reginfo structs for the generic timer registers
to use access functions rather than returning EXCP_UDEF from
their read handlers. In some cases this allows us to remove
a read handler completely....

target-arm: Convert miscellaneous reginfo structs to accessfn

Convert the remaining miscellaneous cases of reginfo read/write
functions returning EXCP_UDEF to use an accessfn instead:
TEEHBR, and the ATS address-translation operations.

target-arm: Log bad system register accesses with LOG_UNIMP

Log guest attempts to access unimplemented system registers via
the LOG_UNIMP reporting mechanism (for both the 32 bit and 64 bit
instruction sets). This is particularly useful for debugging
problems where the guest is trying to use a system register that...

target-arm: Stop underdecoding ARM946 PRBS registers

The ARM946 has 8 PRBS (protection region base and size) registers.
Currently we implement these with a CP_ANY reginfo; however this
underdecodes (since there are 16 possible values of CRm but only
8 registers) and we catch the invalid values in the read and...

target-arm: Split cpreg access checks out from read/write functions

Several of the system registers handled via the ARMCPRegInfo
mechanism have access trap control bits controlling whether the
registers are accessible to lower privilege levels. Replace
the existing mechanism (allowing the read and write functions...

target-arm: Convert performance monitor reginfo to accessfn

Convert the performance monitor reginfo definitions to use
an accessfn rather than returning EXCP_UDEF from read and
write functions. This also allows us to fix a couple of XXX
cases where we weren't imposing the access restrictions on...

target-arm: Restrict check_ap() use of S and R bits to v6 and earlier

The SCTLR bits S and R (8 and 9) only exist in ARMv6 and earlier.
In ARMv7 these bits RAZ, and in ARMv8 they are reassigned. Guard
the use of them in check_ap() so that we don't get incorrect results...

target-arm: Remove unused ARMCPUState sr substruct

Remove the 'struct sr' from ARMCPUState -- it isn't actually used and is
a hangover from the original separate system register implementation used
by the SuSE linux-user-mode-only AArch64 target.
