arm64: defconfig: enable Qualcomm MSM8996 Global Clock Controller as built-in

The commit 8f680c287445 ("arm64: defconfig: Switch msm8996 clk drivers
to module") switched CONFIG_MSM_MMCC_8996 to module, which also resulted
in CONFIG_MSM_GCC_8996 being switched to module. This breaks useful
bootflow for Qualcomm MSM8996 / APQ8096 platforms, because the serial is
not enabled anymore until the GCC module is loaded.
