Traditionally the DFU support is available only
as part 2nd stage boot loader(u-boot) and DFU
is not supported in SPL.

The SPL-DFU feature is useful for boards which
does not have MMC/SD, ethernet boot mechanism
to boot the board and only has USB inteface.

This patch add DFU support in SPL with RAM
memory device support to load and execute u-boot.
And then leverage full functionality DFU in
u-boot to flash boot inital binary images to
factory or bare-metal boards to memory devices
like SPI, eMMC, MMC/SD card using USB interface.

This SPL-DFU support can be enabled through
Menuconfig->Boot Images->Enable SPL-DFU support

Commit 14727120 ("net: asix: fix operation without eeprom")
added a special handling for ASIX 88772B that enable another
type of header. This break the driver in DM mode as the extra handling
needed in the receive path is missing.

However this new header mode is not required and only seems to
increase the code complexity, so this patch revert this part of
commit 14727120.

This also reverts commit 41d1258a
("net: asix: Fix AX88772B when used with DriverModel") of late.

Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

My motivation for this patch is to make reset control handling
optional for generic drivers.

I want to add reset control to drivers/usb/host/ehci-generic.c,
but it is used by several platforms, some will implement a reset
controller driver, some will not.

Add no-op stubs in order to avoid link error for drivers that
implement reset controlling, but still it is optional.

Unlike Linux, nothing about errno.h is arch-specific in U-Boot.
As you see, all of arch/${ARCH}/include/asm/errno.h is just a
wrapper of <asm-generic/errno.h>.  Actually, U-Boot does not
export headers to user-space, so we just have to care about the
consistency in the U-Boot tree.

Now all of include directives for <asm/errno.h> are gone.
