Fix Kconfig: ALWAYS_LOAD_OPROM has unmet dependency VGA_ROM_RUN

Broadwell and Skylake chipsets, along with a few mainboards were
selecting ALWAYS_LOAD_OPROM without making sure that the dependency
for that symbol was met as well.

Looking at the dependencies for VGA_RUN_ROM, we see:
PCI && !PAYLOAD_SEABIOS && !MAINBOARD_DO_NATIVE_VGA_INIT

Since ARCH_X86 selects PCI, that's always met here.
Since Broadwell and Skylake don't have native VGA init yet, that's
not needed.

- Make sure that VGA_RUN_ROM is selected as well.
- Add dependency on !PAYLOAD_SEABIOS for both ALWAYS_LOAD_OPROM and
VGA_RUN_ROM symbols where they're selected.

Fixes Kconfig warning for these boards and chipsets:
warning: (BOARD_SPECIFIC_OPTIONS && BOARD_SPECIFIC_OPTIONS &&
BOARD_SPECIFIC_OPTIONS && CPU_SPECIFIC_OPTIONS && CPU_SPECIFIC_OPTIONS)
selects ALWAYS_LOAD_OPROM which has unmet direct dependencies
(VGA_ROM_RUN)
