[PATCH 6.12.y 1/2] mfd: twl-core: Use i2c_check_functionality as boolean value

[Sasha Levin <sashal@kernel.org>]

From: Thorsten Blum <thorsten.blum@linux.dev>

[ Upstream commit 7ee4fa2674e51a0d100b9240cd8a50355141362f ]

i2c_check_functionality() returns a boolean status rather than an error
code - directly use it as a boolean value.
