soc/intel/alderlake: Remove SOC_INTEL_GFX_MBUS_JOIN config

This patch removes the SOC_INTEL_GFX_MBUS_JOIN configuration option.
Support for fast modeset joining has been added to the mainline i915
kernel driver (https://patchwork.freedesktop.org/series/130480/),
making this coreboot-specific workaround unnecessary.

BUG=b:291885733
TEST=Successful build and boot of google/marasov with single and dual
displays, no redundant boot splash.
