disk: default to HW partition 0 if not specified
Currently, get_device()/get_dev_hwpart() for MMC devices does not select
an explicit HW partition unless the user explicitly requests one, i.e. by
requesting device "mmc 0.0" rather than just "mmc 0". I think it makes
more sense if the default is to select HW partition 0 (main data area)
if the user didn't request a specific partition. Otherwise, the following
happens, which feels wrong:
Select HW partition 1 (boot0):
mmc dev 0 1
Attempts to access SW partition 1 on HW partition 1 (boot0), rather than
SW partition 1 on HW partition 0 (main data area):
ls mmc 0:1 /
With this patch, the second command above re-selects the main data area.
Many device types don't support HW partitions at all, so if HW partition
0 is selected (either explicitly or as the default) and there's no
select_hwpart function, we simply skip attempting to select a HW
partition.
Some MMC devices (i.e. SD cards) don't support HW partitions. However,
this patch still works, since mmc_start_init() sets the current
partition number to 0, and mmc_select_hwpart() succeeds if the requested
partition is already selected.

mtd: nand: omap_elm: use macros for register definitions

- ELM_MAX_ERRORS: ELM can detect upto 16 ECC error when using BCH16 scheme

Current implementation of omap_elm driver uses ECC syndrom length (in 'nibbles')
to differentiate between BCH4/BCH8/BCH16. This patch replaces it with 'bch_type'

always have the common libraries to be linked,
so HOSTLOADLIBES_* can be consolidated a little bit.
