Now that -Wcast-qual hit current, it uncovered an interesting issue.
hpckbd(4) uses pckbd_keydesctab as a based table, patching KB_MACHDEP
entries with information from hpckbdkeymap.h

pckbd_keydesctab is "const" and is placed in the .text - yet hpckbd(4)
patches it successfully. So we have kernel .text kernel-writable.  I
verified it with ddb on hpcsh.  I gather the same is true on other
hpc* ports, or hpckbd(4) would caused access fault.

This looks like something we should fix.

SY, Uwe
