ACPI: Use DEVICE_ATTR_<RW|RO|WO> macros

Browse Source 
[ Upstream commit 0f39ee8324 ]

Instead of open coding DEVICE_ATTR(), use the
DEVICE_ATTR_RW(), DEVICE_ATTR_RO() and DEVICE_ATTR_WO()
macros wherever possible.

This required a few functions to be renamed but the
functionality itself is unchanged.
