Subject: [PATCH 3/3] input: touchscreen: fix link error

Fix link error when TOUCHSCREEN_RASPBERRYPI_FW is enabled as a module
and the dependent module is built-in.
The 'depends on RASPBERRYPI_FIRMWARE' by itself prevents the touchscreen
driver from being built-in when the firmware is configured as a module.
However, the '|| COMPILE_TEST' still allows it unless we explicitly
prevent that configuration with '|| (RASPBERRYPI_FIRMWARE=n &&
COMPILE_TEST)'

ld: drivers/input/touchscreen/raspberrypi-ts.o: in function `rpi_ts_probe':
raspberrypi-ts.c:(.text+0x3a8): undefined reference to `rpi_firmware_get'
ld: raspberrypi-ts.c:(.text+0x3a8): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `rpi_firmware_get'
ld: raspberrypi-ts.c:(.text+0x4c8): undefined reference to `rpi_firmware_property'
ld: raspberrypi-ts.c:(.text+0x4c8): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `rpi_firmware_property'

Rework so that TOUCHSCREEN_RASPBERRYPI_FW depends on
RASPBERRYPI_FIRMWARE=n if COMPILE_TEST is enabled.

Say Y here if you have the official Raspberry Pi 7 inch screen on
your system.
