The BITMAP related operations can now be moved to ./include/linux/bitmap.h
file to mimic the Linux kernel directory tree.

This change also allows to remove the lin_gadget_compat.h header file
(which is a legacy code only for composite U-boot layer).
It was also possible to remove #includes from several USB gadget drivers.

The regs_phy field of the platform data structure for dwc2-otg is
today declared an unsigned int, but will eventually be cast into a
void* for a writel operation.  This triggers errors on modern GCC
versions.

E.g. we get the following error with GCC 6.3:
  drivers/usb/phy/rockchip_usb2_phy.c: In function 'property_enable':
  arch/arm/include/asm/io.h:49:29: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
   #define __arch_putl(v,a)  (*(volatile unsigned int *)(a) = (v))
                               ^
  arch/arm/include/asm/io.h:117:48: note: in expansion of macro '__arch_putl'
   #define writel(v,c) ({ u32 __v = v; __iowmb(); __arch_putl(__v,c); __v; })
                                                  ^~~~~~~~~~~
  drivers/usb/phy/rockchip_usb2_phy.c:61:2: note: in expansion of macro 'writel'
    writel(val, pdata->regs_phy + reg->offset);
    ^~~~~~

This commit changes regs_phy to be a uintptr_t to ensure that it is
large enough to hold any valid pointer (and fix the associated
warning).

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

There was for long time no activity in the mpx5xxx area.
We need to go further and convert to Kconfig, but it
turned out, nobody is interested anymore in mpc5xxx,
so remove it.

The regs_otg field in uintptr_t of the platform data structure for
dwc2-otg has thus far been an unsigned int, but will eventually be
casted into a void*.

This raises the following error with GCC 6.3 and buildman:
  ../drivers/usb/gadget/dwc2_udc_otg.c: In function 'dwc2_udc_probe':
  ../drivers/usb/gadget/dwc2_udc_otg.c:821:8: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
    reg = (struct dwc2_usbotg_reg *)pdata->regs_otg;
          ^

This changes regs_otg to a uintptr_t to ensure that it is large enough
to hold any valid pointer (and fix the associated warning).
