[backport from linux commit 204b885e and 218e180e7]
64 bit processors are becomming more and more popular.
lower_32_bits and upper_32_bits save our labor doing
shifts/manipulations like (u32)(n) and (u32)((n) >> 32).
They are good helpers in both little and big endian cases.
Port these two functions here from Linux:include/linux/kernel.h,
cater the comment message to little/big endian cases.
Later on, developers could include linux/compat.h if they want to
use these two functions.

Since kernel code current use many dev_xxx() instead of using printk. To
compatible, move those dev_xxx from usb driver to linux/compat.h. Then all
driver code can use dev_err, dev_info and dev_vdbg.
This patch also removed duplicated macro definitions in usb driver.

fixup __iomem, __user definitions in compat.h code appears to be placed
there as a cover up from a code import from linux when u-boot didn't yet
have a compiler.h, introduced by commit
932394ac43e2e778e664eeb6e456fecd0fae6e59 "Rewrite of NAND code based on
what is in 2.6.12 Linux kernel".

Merge our duplicate definitions with the common header.
Also fix drivers/usb/gadget/s3c_udc_otg_xfer_dma.c to
use min() instead of min_t() since we remove the latter
from compat.h.
Additionally use memalign() directly as the lin_gadget
specific kmalloc() macro is removed from lin_gadget_compat.h
by this patch.

This lets us use it in more places than just mtd code.
