[POWERPC] Remove todc code from ARCH=powerpc
Apparently we've copied the todc drivers, for various RTCs used in embedded machines from ARCH=ppc to ARCH=powerpc, despite the fact that it's never used in the latter. This patch removes it. If we ever need these drivers (which we probably shouldn't now the RTC class stuff is in), we can transfer them one by one from ARCH=ppc, removing from the hideous abomination which is the todc "infrastructure".

26 * Depending on the hardware on your board and your board design, the
27 * RTC/NVRAM may be accessed either directly (like normal memory) or via
28 * address/data registers. If your board uses the direct method, set
29 * 'nvram_data' to the base address of your nvram and leave 'nvram_as0' and
30 * 'nvram_as1' NULL. If your board uses address/data regs to access nvram,
31 * set 'nvram_as0' to the address of the lower byte, set 'nvram_as1' to the
32 * address of the upper byte (leave NULL if using mc146818), and set
33 * 'nvram_data' to the address of the 8-bit data register.
34 *
35 * Note: Even though the documentation for the various RTC chips say that it
36 * take up to a second before it starts updating once the 'R' bit is
37 * cleared, they always seem to update even though we bang on it many
38 * times a second. This is true, except for the Dallas Semi 1746/1747
39 * (possibly others). Those chips seem to have a real problem whenever
40 * we set the 'R' bit before reading them, they basically stop counting.
