If a specific configuraion is selected by the bootm command, e.g. with
'bootm 84000000#recoveryconf' we must honour this for not just the kernel,
but also the ramdisk and FDT.
In the conversion to using a common fit_image_load() function for loading
images from FITs (commits a51ec63 and 53f375f) this feature was lost.
Reinstate it by passing the selected configuration back from
fit_image_load() to boot_get_kernel(), then use this configuration
(which is stored in images->fit_uname_cfg) in both boot_get_ramdisk()
and boot_get_fdt().

With 35fc84fa1 [Refactor the bootm command to reduce code duplication]
we stopped checking the return value of bootm_load_os (unintentionally!)
and simply returned if we had a non-zero return value from the function.
This broke the valid case of a legacy image file of a single kernel
loaded into an overlapping memory area (the default way of booting
nearly all TI platforms).
The best way to fix this problem in the new code is to make
bootm_load_os be the one to see if we have a problem with this, and if
it's fatal return BOOTM_ERR_RESET and if it's not BOOTM_ERR_OVERLAP, so
that we can avoid calling lmb_reserve() but continue with booting. We
however still need to handle the other BOOTM_ERR values so re-work
do_bootm_states so that we have an error handler at the bottom we can
goto for problems from bootm_load_os, or problems from the other callers
(as the code was before). Add a comment to do_bootm_states noting the
existing restriction on negative return values.

With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type,
which is required to represent block numbers for storage devices that
exceed 2TiB (the block size usually is 512B), e.g. recent hard drives.
For some obscure reason, the current U-Boot code uses lbaint_t for the
number of blocks to read (a rather optimistic estimation of how RAM
sizes will evolve), but not for the starting address. Trying to access
blocks beyond the 2TiB boundary will simply wrap around and read a
block within the 0..2TiB range.
We now use lbaint_t for block start addresses, too. This required
changes to all block drivers as the signature of block_read(),
block_write() and block_erase() in block_dev_desc_t changed.
