[PATCH] ACPI / platform: drop redundant ACPI_HANDLE check

[Josh Cartwright <joshc@codeaurora.org>]

The acpi_dev_pm_attach/_detach functions perform their own checks to
ensure the device has an ACPI companion.  It is not necessary for the
caller to do so.

This mirrors what other busses with ACPI dev PM support do (i2c, spi,
sdio).
