USB-serial updates for v4.5-rc1
These updates add support for Moxa UPort 1100-series devices through a
new mxu11x0 driver.
The cp210x driver gains proper support for cp2108 devices by working
around a couple of firmware bugs, and generic wait-until-sent support
(e.g. for tcdrain) is also added.
Included are also some general clean ups.

Add a driver which supports :
- UPort 1110 : 1 port RS-232 USB to Serial Hub.
- UPort 1130 : 1 port RS-422/485 USB to Serial Hub.
- UPort 1130I : 1 port RS-422/485 USB to Serial Hub with Isolation.
- UPort 1150 : 1 port RS-232/422/485 USB to Serial Hub.
- UPort 1150I : 1 port RS-232/422/485 USB to Serial Hub with Isolation.
This driver is based on GPL MOXA driver written by Hen Huang and available
on MOXA website. The original driver was based on io_ti serial driver.

phy: for 4.5
*) new PHY driver for hi6220 usb and rcar gen3 usb2
*) deprecate phy-omap-control driver. phy-omap-control driver was added
when there was no proper infrastructure for doing control module
initialization. The phy-omap-control driver is not an 'actual' PHY
driver and it was just a hack to do PHY related control module
initialization. Now with SYSCON framework in the kernel, control
module setttings can be done using APIs provided by syscon.
*) usbphy-internal pll creates the needed 480MHz and is also a

When sysrq is triggered from console, serial driver for SUN hypervisor
console receives a console break and enables the sysrq. It expects a valid
sysrq char following with break. Meanwhile if driver receives 'NULL'
ASCII char then it disables sysrq and sysrq handler will never be invoked.
This fix skips calling uart sysrq handler when 'NULL' is received while
sysrq is enabled.

In specific conditions (involving usb hubs) dwc2 devices can create a
lot of interrupts, even to the point of overwhelming devices running
at low frequencies. Some devices need to do special clock handling
at shutdown-time which may bring the system clock below the threshold
of being able to handle the dwc2 interrupts. Disabling dwc2-irqs
in a shutdown callbacks prevents reboots/poweroffs from getting stuck
in such cases.
The hsotg struct already contains an unused irq element, so we can
just use it to store the irq number for the shutdown callback.
