[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.

There is only one line diff between LEON2 and LEON3 linker scripts:

  -             arch/sparc/cpu/leon2/start.o (.text)
  +             arch/sparc/cpu/leon3/start.o (.text)

They can be written in the same way:

                */start.o (.text)

So, board/gaisler/grsim_leon2/u-boot.lds
and arch/sparc/cpu/leon3/u-boot.lds
can be merged into arch/sparc/cpu/u-boot.lds.

 - board/gaisler/gr_cpci_ax2000/u-boot.lds
 - board/gaisler/gr_ep2s60/u-boot.lds
 - board/gaisler/gr_xc3s_1500/u-boot.lds

are the same (except cosmetic differences such as indentation).

This commit merges them into arch/sparc/cpu/leon3/u-boot.lds.

Current code uses the preprocessor to change an else case
to a statement without any if condition at all. Although
this works, change the optional code to return early, so
all optional code is contained within a single #ifdef.

When static inline is used in a header file the function
should preferably be inlined and if not possible made a
static function. When declared inside a c file there is a
static function, which might be inlined. Since SPL uses a
define to declare the static inline it becomes part of the
c file although it is declared in a header and clang will
warn that you have introduced unused static functions. Add
maybe_unused to prevent such warnings.

Going forward, "-" stands for no board directory

The boards.cfg file has allowed to use "-" for the board (= 6th) field
if the board name is the same as the 7th field.

But I notice one problem.
Because tools/reformat.py sorts the lines in the simple alphabetical
order (= the order of character code), some entries for the same board
are not lined up together.

For example, "bf527-ezkit" and "bf527-ezkit-v2" share the same board.
But they are located separately because "bf527-ezkit" fills the board
field with "-" whereas "bf527-ezkit-v2" specifies it explicitely.

The similar things can be seen:
 - between "trizepsive" and "polaris"
 - between "RRvision" and "RRvision_LCD"
 - between "korat" and "korat_perm"
 - between "lwmon5" and "lcd4_lwmon5"

This commit was generated by the following command:

awk '$6 == "-" { $6 = $7 } { print }' boards.cfg \
  | tools/reformat.py -i -d '-' -s 8  > boards0.cfg; \
  mv boards0.cfg boards.cfg

The pad settings for DISP0_DATA02 and DISP0_DAT10 were not
set in the same way as DISP0_DAT00-23, causing much flicker
in parallel RGB displays on Dual-Lite and Solo processors.

These settings now match the i.MX6 Dual and Quad core versions.

Note that this fixes a regression in commit b47abc36 and that
this is the second time we've had a regression on these two
pads (See commit e654ddf7).
