[PATCH]Make LPT ports configurable on various i945/ich7 boards

[Georgi, Patrick]

Hi,

attached patch adds a new CMOS variable which triggers activation of the
LPT port. With the CMOS variable set, LPT is found by SeaBIOS, with the
variable reset, it's not.

There's probably a better place for the code to end up in, but this has
to do for now.

Do we want a wrapper like this?

#define read_cmos_option(option, default)       \
        read_option(CMOS_VSTART_##option, CMOS_VLEN_##option, default)
