ARM: get temp.c in.

No code changes, but quite a few removals of __ARMEL_NOTYET__
guards. 20 such guards left.

Test: M105 should work and report plausible temperatures.

Current code size:

    SIZES          ARM...     lpc1114
    FLASH  :  9460 bytes          29%
    RAM    :  1258 bytes          31%
    EEPROM :     0 bytes           0%
