This patch protects the mod->irq_bempsts and mod->irq_brdysts by
spin lock in the usbhs_status_get_each_irq() because other functions
will write them during spin lock. Otherwise, the driver will clears
the BRDYSTS and/or BEMPSTS wrongly, and then, the transaction will not
finish.
Also since the driver should use the INTSTS0 and BRDYSTS and BEMPSTS
as the same timing, the patch protects them.Signed-off-by: Yoshihiro Shimoda

USB gadget patches from Felipe:
"usb: gadget: patches for v3.8renesas_usbhs implements ->pullup() method, switches over
to devm_request_irq(), adds support for DMA Engine and
got a few miscelaneous cleanups.The NCM gadget got an endianness fix and the Ethernet
gadget a frame size fix.We're finally removing the g_file_storage gadget and
sticking to g_mass_storage and the new tcm_usb_gadget
gadgets since that was a huge duplicaton of effort anyway.While removing g_file_storage, we also had to fix a bunch
of defconfigs which were still pointing to the old gadget.There's a big series getting us closer to being able to
introduce our configfs interface. The series converts
functions into loadable modules which will, eventually,
be registered to the configfs interface.Other than that there's the usual typo fixes and miscelaneous
cleanups all over the place."

When interrupt happened, renesas_usbhs driver gets irq status
by usbhs_status_get_each_irq(), and cleared all status by using 0.
But, this method is incorrect,
since extra interrupt might occur between them.
This patch cleared corresponding bits onlySigned-off-by: Kuninori Morimoto

When IORESOURCE_IRQ_SHAREABLE is set, the irq handler may be called
even if the interupt of the USB module doesn't happen. So, it may
clear the interrupt flags by mistake. This patch fixes it.Signed-off-by: Yoshihiro Shimoda

renesas_usbhs has default callback functions and settings.
And it tried overwrite to platform private data
if platform doesn't have them.
So, if renesas_usbhs was compiled as module,
it will be hung-up on 2nd insmod.
This patch fixup it.

current mod_gadget had got usb speed on
usbhsg_irq_dev_state() which is status change interrupt callback function.
And the usb speed data was included in its parameter.But this style works for mod_gadget,
but doesn't work for mod_host which
isn't interrupted when device status was changed.This patch add usbhs_bus_get_speed() to solve this issue.

Current renesas_usbhs was designed to save power when USB is not connected.
And it assumed platform uses callback to notify connection/disconnection
by external interrupt.But some SuperH / platform board doesn't have such feature.
This patch adds autonomy mode which detect USB connection/disconnection
by internal interrupt.
But power will be always ON when autonomy mode is selected.Signed-off-by: Kuninori Morimoto
