Do not config MUSB to highspeed mode if CONFIG_USB_GADGET_DUALSPEED
is not set, in which case Ether gadget only operates in fullspeed.

On TI AM335x devices, MUSB has bulk split/combine feature enabled
in the ConfigData register, but the current MUSB driver does not
support it yet. Therefore, disable the feature for now, until the
driver adds the support.
One usecase which is broken because of this feature is that Ether
gadget stops working in Fullspeed mode (by un-defining
CONFIG_USB_GADGET_DUALSPEED)
After desabled this feature, MUSB driver send packets in proper size
(no more than 64 bytes) in Fullspeed mode.
This has been validated with Ether gadget in Fullspeed mode on AM335x
EVM.

'bool' is defined in random places. This patch consolidates them into a
single header file include/linux/types.h, using stdbool.h introduced in C99.
All other #define, typedef and enum are removed. They are all consistent with
true = 1, false = 0.
Replace FALSE, False with false. Replace TRUE, True with true.
Skip *.py, *.php, lib/* files.

Backend driver for MUSB OTG controllers found on TI AM35x.
It seems that on AM35X interrupt status registers can be updated
_before_ core registers. As we don't use true interrupts in U-Boot
and poll interrupt status registers instead this can result in
interrupt handler being called with non-updated core registers.
This confuses the code and result in hanged transfers.
Add a small delay in am35x_interrupt as a workaround.

Existing U-Boot musb driver has no support for the new gadget framework
and also seems to have other limitations. As gadget framework is ported
from Linux it seems pretty natural to port musb gadget driver as well.
This driver supports both host and peripheral modes.
This is not a replacement for current musb driver (at least now) as
there are still some consumers of the old UDC interface.
No DMA operation support included, CONFIG_MUSB_PIO_ONLY should be
defined.
Virtual root hub device is not implemented.
Known problems: with no devices connected usb_lowlevel_start() fails.
