nds32: introduce macros for bit manipulation
U-Boot does not compile for the adp-ag101 boards since
commit f6c3b34697bf8bf05cb4e81c2fd3cadb9a98daea (mmc:
update Faraday FTSDC010 for rw performance)
The driver assumes that the bit manipulation macros
are provided by all architectures. This is not the
case for nds32 and it causes a build error like this:
ftsdc010_mci.c: In function 'ftsdc010_clkset':
ftsdc010_mci.c:118: warning: implicit declaration of function 'setbits_le32'
ftsdc010_mci.c:123: warning: implicit declaration of function 'clrbits_le32'
drivers/mmc/libmmc.o: In function `ftsdc010_request':
/devel/u-boot.git/drivers/mmc/ftsdc010_mci.c:234: undefined reference to `setbits_le32'

/devel/u-boot.git/drivers/mmc/ftsdc010_mci.c:123: undefined reference to `setbits_le32'
/devel/u-boot.git/drivers/mmc/ftsdc010_mci.c:123: undefined reference to `setbits_le32'
The patch adds bit manipulation macros for the
nds32 architecture to avoid the errors. The macros
are copied from the ARM implementation.
Compile tested only.
