Uwe Hermann 30d789bcbd Fix the NVRAM access functions to work correctly for the
upper 128 bytes of NVRAM (if enabled).

For most chipsets this means using I/O ports 0x72/0x73, but at least
on some VIA chipsets (I tested the VIA VT8237R on actual hardware)
these ports won't work and you have to use 0x74/0x75. Thus, make this
a Kconfig option for now.

Uwe Hermann 8cc38d2f13 Add initial support for some basic CMOS read/write functions and the
bcd2dec()/dec2bcd() functions we'll need for (among other things)
converting some date/time parameters in CMOS.

Jonathan A. Kollasch b0e3f39a39 Make cursor positioning work by using both halves of the
VGA cursor position register.
   
Have vga_scroll_up() and vga_clear_line() present row/column
arguments to the VIDEO() macro in the right order.

Uwe Hermann 14a3feb068 Fix code to allow usage of -Wall in libpayload and the sample (trivial).
This even fixes two bugs:

 - get_cpu_speed() didn't return a value.

 - The line
     win->_color - PAIR_NUMBER(0);
   should actually be
     win->_color = PAIR_NUMBER(0);
