Subject: ARM: imx6: add missing BM_CLPCR_BYPASS_PMIC_READY setting for imx6sx

From: Anson Huang <Anson.Huang@nxp.com>

commit 8aade778f787305fdbfd3c1d54e6b583601b5902 upstream.

i.MX6SX has bypass PMIC ready function, as this function
is normally NOT enabled on the board design, so we need
to bypass the PMIC ready pin check during DSM mode resume
flow, otherwise, the internal DSM resume logic will be
waiting for this signal to be ready forever and cause
resume fail.
