drm/msm/a6xx: add CONFIG_QCOM_LLCC dependency

Browse Source 
When LLCC support is in a loadable module, the adreno support
cannot be built-in:

aarch64-linux-ld: drivers/gpu/drm/msm/adreno/a6xx_gpu.o: in function `a6xx_gpu_init':
a6xx_gpu.c:(.text+0xe0): undefined reference to `llcc_slice_getd'
a6xx_gpu.c:(.text+0xe0): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `llcc_slice_getd'
aarch64-linux-ld: a6xx_gpu.c:(.text+0xec): undefined reference to `llcc_slice_getd'
a6xx_gpu.c:(.text+0xec): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `llcc_slice_getd'
aarch64-linux-ld: drivers/gpu/drm/msm/adreno/a6xx_gpu.o: in function `a6xx_destroy':
a6xx_gpu.c:(.text+0x274): undefined reference to `llcc_slice_putd'
a6xx_gpu.c:(.text+0x274): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `llcc_slice_putd'
aarch64-linux-ld: a6xx_gpu.c:(.text+0x27c): undefined reference to `llcc_slice_putd'

Add a Kconfig dependency that disallows the broken configuration
but allows all working ones.
