parisc: Remove unnecessary macros from entry.S

The EXTR, DEP and DEPI macros are unnecessary. There are PA 1.X pneumonics available with the same functionality, and the DEP and DEPI macros conflict with assembler pneumonics. Tested on a variety of 32 and 64-bit systems. Signed-off-by: John David Anglin <[email protected]> Signed-off-by: Kyle McMartin <[email protected]>
