initrdscripts: Update install.sh to work with mmc devices
Fixes [YOCTO #2385]
The installer only searches for hd[ab] sd[ab]. Some newer BSPs have mmcblk
devices that should be used as the install target. These devices also have a
partition prefix (mmcblk0p1 instead of mmcblk01). As they are detected
asynchronously, it is necessary to add the rootwait kernel parameter to avoid
a race condition trying to mount the root device.
As BSPs like the FRI2 and the sys940x have mmc devices and will have a 1.2
release, we should push this to 1.2.1. The changes are perfectly contained and
easily verified.
Test for an mmcblk device and add the p partition prefix if necessary. Add the
rootwait kernel parameter when an mmcblk device is detected. Replace the series
of explicit umount commands with a single umount using a wildcard. This will
find all the partitions and will not try to unmount non-existant devices. Avoid
copy and paste errors by replacing /dev/${device}${pX} references with the
previously assigned rootfs, bootfs, and swap variables.
These changes have been tested on the FRI2 Sato image which installed to
/dev/mmcblk0 as well as the N450 Sato image which installed to /dev/sda. Both
were successful.
