amd/00730F01: Clean the Microcode updating

According to the comments of
https://review.coreboot.org/c/coreboot/+/41719
, which is about Microcode patch for amd/picasso.
Change the code with the same way.

The changes include:
1. combine the microcode_xxx.c and update_microcode.c
   into one source.
2. Redefine the microcode updating function to eliminate
   the parameter. Get the revision ID in the black box.
   Reduce the depth of function calls.
3. Get the revision ID by bitwise calculation instead of
   lookup table.
4. Reduce the confusing type casts.
5. Squash some lines.

We do not change the way it used to be. The code assume
only one microcode is integrated in CBFS. If needed in future,
41719 is the example of integrating multiple binaries.

And, 41719 depends on the definition in this patch.
