Merge branch 'drivers/ocp2scp' into next/drivers

Patch series from Kishon Vijay Abraham I <kishon@ti.com>:

This patch series is done as a preparatory step for adding phy drivers
for dwc3 and musb.

This series adds a new driver for ocp2scp (only dt) to which phy
drivers are connected.

Since currently there is no generic way to create a child device along
with doing a pm_runtime_enable (the exact requirement for ocp2scp), I'm
creating a separate driver for ocp2scp.

Changes from v3:
No functional changes. Fixed few comments on filling module details.

Changes from v2:
Fixed Felipe's comments to avoid using arch_initcall and make dependent
drivers return -EPROBE_DEFER case this isn't ready yet.

Changes from v1:
Fixed Sergei's comments to remove the address in the node name of ocp2scp
since the ocp2scp node doesn't have a reg property.

Changes from [RFC PATCH v2 0/2] omap: add ocp2scp as a misc driver:
Created a new folder drivers/bus and moved ocp2scp driver from misc to
drivers/bus.

This patch was developed and tested on
git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb.git
