*sigh*. This, of course, should have been #ifdef CONFIG_PM. Fixed
v3 below.

Subject: [PATCH v3] usb: phy: msm: fix compilation errors when !CONFIG_PM_SLEEP
Both the PM_RUNTIME and PM_SLEEP callbacks call into the common
msm_otg_{suspend,resume} routines, however these routines are only being
built when CONFIG_PM_SLEEP. In addition, msm_otg_{suspend,resume} also
depends on msm_hsusb_config_vddcx(), which is only built when
CONFIG_PM_SLEEP.
Fix the CONFIG_PM_RUNTIME, !CONFIG_PM_SLEEP case by changing the
preprocessor conditional, and moving msm_hsusb_config_vddcx().
While we're here, eliminate the CONFIG_PM conditional for setting
up the dev_pm_ops.
This address the following errors Russell King has hit doing randconfig
builds:

drivers/usb/phy/phy-msm-usb.c:1691:2: error: implicit declaration of function 'msm_otg_suspend'
