spl: mmc: Rename spl_boot_mode() to spl_mmc_boot_mode()

Browse Source 
The function's name is misleading as one might think it is used
generally to select the boot-mode when in reality it is only used by the
MMC driver to find out in what way it should try reading U-Boot Proper
from a device (either using a filesystem, a raw sector/partition, or an
eMMC boot partition).

Rename it to spl_mmc_boot_mode() to make it more obvious what this
function is about.

* If not overridden, it is weakly defined in common/spl/spl_mmc.c.

* Note: It is important to use the boot_device parameter instead of e.g.
* spl_boot_device() as U-Boot is not always loaded from the same device as SPL.
