[PATCH] HID: lenovo: select CONFIG_ACPI_PLATFORM_PROFILE

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

A previous patch tried to fix this link failure:

x86_64-linux-ld: drivers/hid/hid-lenovo.o: in function `lenovo_raw_event':
hid-lenovo.c:(.text+0x22c): undefined reference to `platform_profile_cycle'

but got it wrong in three ways:

 - the link failure still exists with CONFIG_ACPI_PLATFORM_PROFILE=m
   when hid-lenovo is built-in

 - There is no way to manually enable CONFIG_ACPI_PLATFORM_PROFILE, as
   it is intended to be selected by its users.

Remove the broken #if check again and instead select the symbol like
the other users do. This requires adding a dependency on CONFIG_ACPI.

Fixes: 52e7d1f7c2fd ("HID: lenovo: Fix undefined platform_profile_cycle in ThinkPad X12 keyboard patch")
