[PATCH] common: splash_source: Don't compile ubifs splash cmd for SPL build

[Devarsh Thakkar <devarsht@ti.com>]

Don't compile ubifs splash mount command for SPL build as this command
is not supported (and also not enabled) during SPL stage.

This fixes below compilation error, when CONFIG_CMD_UBIFS is enabled in
defconfig along with splash screen enabled at SPL stage.

Fixes below error when CONFIG_CMD_UBIFS is enabled in defconfig along
with splash screen at SPL stage:

"aarch64-none-linux-gnu-ld.bfd: common/cli.o: in function `run_command':
u-boot-next/u-boot/common/cli.c:51: undefined reference to
`parse_string_outer'
u-boot-next/u-boot/common/cli.c:51:(.text.run_command+0x10): relocation
truncated to fit: R_AARCH64_JUMP26 against undefined symbol
