util/amdfwtool: Remove duplicate PSP2 support
There are effectively two unique sets of arguments for the utility, causing one of two tables to be constructed. Both tables are identical, however, and therefore the only practical difference is the offset in the Embedded Firmware Structure which holds the pointer to the table. This patch is part 2 of 2 to reduce the number of command-line options to amdfwtool. Part 1 added the --combo-capable option that helps put the PSP directory pointer in the correct location. Part 2 removes the duplicated table, the support code, options, and updates the usage text. TEST=Build before/after images for grunt, bettong, apu2, and diff hexdumps of the amdfw.rom files. Built/ran grunt with PSP_COMBO defined as 1.

+ * Beginning with Family 15h Models 70h-7F, a.k.a Stoney Ridge, the PSP
+ * can support an optional "combo" implementation. If the PSP sees the

+ * tables. Using this, support for multiple product generations may be
+ * built into one image. If the PSP$ cookie is found, the table is a
+ * normal directory table.
+ *
+ * Modern generations supporting the combo directories require the
+ * pointer to be at offset 0x14 of the Embedded Firmware Structure,
+ * regardless of the type of directory used. The --combo-capable
+ * argument enforces this placement.
