9441cd9446 scamp.c: Fix 64-bit integer-as-pointer use for bank number warning 
Patch from davefiddes. Original commit message :

The bank number is stored in a pointer value but is used exclusively as a
bank number integer reference. To do this safely it needs to be an intptr_t.

e3fd8698df Remove faulty cyrix special register read access 
Patch from davefiddes. Original commit message :

GCC 10.1 reports this line as being logically always false so will never run.
On inspection it may be that this was intended to be:

   if ((cyrix_addr & 0xf0) == 0xc0) return 0xff;

According to the IBM 6X86MX Microprocessor Databook
(http://datasheets.chipdb.org/IBM/x86/6x86MX/mx_full.pdf) this would correspond
to the Address Region 0 - 3 registers but omit Address Region 4 - 7 registers
which doesn't seem to make a lot of sense.

Delete the code as the default response from the function is to return 0xff
and this is what its behviour up until now has been.
