[flashrom] [PATCH] Compile fixes, update README

[Carl-Daniel Hailfinger]

I wanted to tag 0.9.3, but then I noticed that compilation was broken in
a few cases, and the README had insufficient information.
Fix that.

In detail:
CONFIG_BITBANG_SPI was not selected if CONFIG_NICINTEL_SPI was on by
default.
Wiki output was missing all flash chips if CONFIG_INTERNAL was not selected.
ft2232_spi used possibly negative indices in the toupper() function/array.
Software requirements on non-Linux/FreeBSD/OpenBSD operating systems
were missing.
Non-x86 compilation does not work with the default programmer set, so
list the make parameters which result in a working build.
