nb/amd/amdht: Use standard coreboot assertions
The amdht code currently relies on an idiosyncratic ASSERT() macro, which actually doesn't do anything right now, and even it did would only print a janky error message. Replace this with the normal ASSERT() macro from <assert.h>. The default behaviour now is to print an error message but do nothing else, and failed assertions will only halt if you enable FATAL_ASSERT, in which case, well, you asked for it.
