Instead of using variable length array, use a static length equal to the size of the ffs->ev.types array. This gets rid of a sparse warning: drivers/usb/gadget/function/f_fs.c:401:44: warning: Variable length array is used. and makes it more explicit that the array has a very tight upper size limit. Also add some more documentation about the ev.types array and how its size is limited and affects the rest of the code.

Add support for vbus detection and power supply. This code is more or less stolen from phy-gpio-vbus-usb.c, and aims at providing a detection mechanism for VBus (ie. usb cable plug) based on a GPIO line, and a power supply activation which draws current from the VBus.

Change internal gpio handling from integer gpios into gpio descriptors. This change only addresses the internal API and device-tree/ACPI, while the legacy platform data remains integer space based. This change is only build compile tested, and very prone to error. I leave this comment for now in the commit message so that this patch gets some testing as I'm pretty sure it's buggy.

at91sam9g45 and at91sam9x5 SoCs have an hardware bug forcing us to generate a pulse on the BIAS signal on "USB end of reset” and “USB end of resume" events.

at91sam9rl SoC has an erratum forcing us to toggle the BIAS on USB suspend/resume events. This specific handling is only activated when CONFIG_ARCH_AT91SAM9RL is set and this option is only set when building a non-DT kernel, which is problematic since non-DT support for at91sam9rl SoC has been removed. Rework the toggle_bias implementation to attach it to the "at91sam9rl-udc" compatible string. Add new compatible strings to avoid executing at91sam9rl erratum handling on other SoCs.

For some user cases, like plug out and replug in usb device during the system suspend, the speed negotiation will be error due to host doesn't know the device's disconnection, and it still hopes the high speed device, but the device backs to "powered" state which its high speed termination is not enabled, the usb core calls the PHY's disconnect notifier with "full speed", it will NOT take effect at all. If the usb core calls disconnect notifer, the port change must happen, so it is safe to disable high speed disconenct detector, since connect notifier will be called soon if the device is still connected on the port, and we will enable high speed disconnect detector at that time.

This patch fixes in simpler way the bug described in [1] and [2]. It looks like DWC2 is the only UDC driver that doesn't force usb requests to complete in ep_disable() function. This causes described problem, because we have no guarantee that all requests will be completed before unbind of usb function. To fix this problem we force all requests of disabled endpoint to complete. Also currently running request is not handled. This allowed to simplify code of kill_all_requests() function, because 'force' parameter is always set to true, so we don't need it anymore. In s3c_hsotg_rx_data() we change function used to print message when active request is NULL from dev_warn() to dev_dbg(), because such situation is harmless for driver and now it can take place during normal endpoint disabling.

irqs_superspeed calls ep_stall instead of set/clear_halt, due to a workaround for SS seqnum. Create a function with the workaround and call set/clear_halt instead.
