[PATCH] arm64: fix boolconv.cocci warnings

[kernel test robot]

From: kernel test robot <lkp at intel.com>

arch/arm64/kernel/acpi.c:71:26-31: WARNING: conversion to bool not needed here

 Remove unneeded conversion to bool

Semantic patch information:
 Relational and logical operators evaluate to bool,
 explicit conversion is overly verbose and unneeded.
