Currently, if a device read request is done that does not begin or end
on a sector boundary a stack allocated bounce buffer is used to perform
the read, and then just the part of the sector that is needed is copied
into the users buffer. This stack allocation can mean that the bounce
buffer will not be aligned to the dcache line size. This is a problem
when caches are enabled because unaligned cache invalidates are not
safe.
This patch uses ALLOC_CACHE_ALIGN_BUFFER to create a stack allocated
cache line size aligned bounce buffer.

Previously reading or writing zero full sectors (reading the end of
one sector and the beginning of the next for example) was special
cased and involved stack allocating a second sector buffer. This
change uses the same code path for this case as well as when there
are a non-zero number of full sectors to access. The result is
easier to read and reduces the maximum stack used.

Fix all checkpatch violations in the low level Ext2 block
device reading code. This is done in preparation for cleaning
up the partial sector access code.

The ext2 aligned process will corrupt the key
data struct, the patch fix this.

Fixed some broken instances of "#ifdef CMD_CFG_IDE" too.
Those always evaluated TRUE, and thus were always compiled
even when IDE really wasn't defined/wanted.

This is a compatibility step that allows both the older form
and the new form to co-exist for a while until the older can
be removed entirely.
All transformations are of the form:
Before:
#if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT)
After:
#if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT)
