Subject: [PATCH] platform/x86: system76_acpi: fix Kconfig dependencies

From: Arnd Bergmann <arnd@...db.de>

When CONFIG_INPUT is disabled, this driver now fails to link:

ld.lld: error: undefined symbol: devm_input_allocate_device
>>> referenced by system76_acpi.c
>>>               platform/x86/system76_acpi.o:(system76_add) in archive drivers/built-in.a

ld.lld: error: undefined symbol: input_set_capability
>>> referenced by system76_acpi.c
>>>               platform/x86/system76_acpi.o:(system76_add) in archive drivers/built-in.a

ld.lld: error: undefined symbol: devm_hwmon_device_register_with_info
>>> referenced by system76_acpi.c
>>>               platform/x86/system76_acpi.o:(system76_add) in archive drivers/built-in.a

ld.lld: error: undefined symbol: battery_hook_unregister
>>> referenced by system76_acpi.c
>>>               platform/x86/system76_acpi.o:(system76_remove) in archive drivers/built-in.a

Add Kconfig dependencies for each of these three.

Fixes: 0de30fc684b3 ("platform/x86: system76_acpi: Replace Fn+F2 function for OLED models")
Fixes: 95563d45b5da ("platform/x86: system76_acpi: Report temperature and fan speed")
Fixes: 76f7eba3e0a2 ("platform/x86: system76_acpi: Add battery charging thresholds")
