This function does not modify the device to change it to use const *, so
that callers with a const udevice * can call it without a cast.

Add getter function which permits adjusting the maximum number of
blocks that could be read in a single sustained read transfer based
on the location of the source/target buffer and length, before such
transfer starts.

This is mainly useful on systems which have various DMA restrictions
for different memory locations, e.g. DMA limited to 32bit addresses,
and where a bounce buffer is used to work around such restrictions.
Since the U-Boot bounce buffer is mallocated, it's size is limited
by the malloc area size, and the read transfer to such a buffer must
also be limited. However, as not all areas are limited equally, the
b_max should be adjusted accordinly as needed to avoid degrading
performance unnecessarily.

MMC_LEGACY & SD_LEGACY are not differentiated timings in the spec and
don't have any meaningful differences. Therefore, get rid of all
references to SD_LEGACY and use MMC_LEGACY to mean both of them.

This header uses bd_t without including its definition.

Change it to (struct bd_info), and add the forward declaration
to specify it as a structure.
