Runtime routine to detect the right register depending on the 16 bit offset part

This function is only used by the functions below.
Depending on the compiler options -Cp different versions of _GET_PAGE_REG are produced.
Arguments :
- Y : offset part of an address
Result :
if address Y is controlled by a page register :
- X : address of page register if Y is controlled by an page register
- Zero flag cleared
- all other registers remain unchanged
if address Y is not controlled by a page register :
- Zero flag is set
- all registers remain unchanged
