doc: Remove the obsolete README.mpc74xx file

Support for the PPC74xx processors has been removed in commit
d928664f41 ("powerpc: 74xx_7xx: remove 74xx_7xx cpu support")
more than 6 years ago already. So the corresponding README file
can now be removed, too.

-This file contains status information for the port of U-Boot to the
-Motorola mpc74xx series of CPUs.

-Currently the support for these CPUs is pretty minimal, but enough to
-get things going.  (much like the support for the Galileo Eval Board)
-
-There is a framework in place to enable the L2 cache, and to program
-the BATs.  Currently, there are still problems with the code which
-sets up the L2 cache, so it's not enabled. (IMHO, it shouldn't be
-anyway).  Additionally, there is support for enabling the MMU, which
-we also don't do.  The BATs are programmed just for the benefit of
-jumping into Linux in a sane configuration.
-
-Most of the code was based on other cpus supported by U-Boot.
-
-If you find any errors in the CPU setup code, please send us a note.
-
-Thanks,
-Josh
