init.sh: don't mount /sdcard

The needed device nodes are not created and /sdcard can't be mounted.

Instead of creating the device nods, the mount command is removed.
This means that the flash will never be automatically re-started
after the conversion if the zip is inside the external SD.

This prevents conflicts with the mountpoints. recovery mounts
automatically the external SD card in /sdcard if extendedcommand is
found. Normally it's mounted in /emmc, which means that the path to
the zip is wrong in this case and without the proper mount commands
the flash will always abort and the device repeatedly rebooted.

Also, unmount /emmc, the content of /dev is deleted right before the
execution of /init and recovery will unmount it anyway.
Updated README.md

Added information about new branches and instructions to build both the ROM and the kernel.

latona: changes for ondemandboost

Set ondemandboost on boot to set the default boostfreq and then
set ondemand as default governor.
init: set svnet permissions

Needed for DeviceParts
DeviceParts: svent wakelock control
Revert "latona: fix UMS issues"

This workaround is no more required.

This reverts commit 206f6a1c0b9f7bff9cb43329daa939f49b1753f5.
Increase PVR parameter buffer size

The default of 2 MB is far too small for the complex OpenGL rendering
used in the Android UI in ICS and up.  Instead, boost the param buffer
size to 12 MB, which improves performance.

XXX TODO: http://processors.wiki.ti.com/index.php/SGXDbg recommends 16
MB or larger, but this causes SurfaceFlinger to crash and burn.
latona: loop ringtones
latona: cleanup

* Disable unsupported/not needed features.
* Remove deprecated prop.
* Don't use a prebuilt egl.cfg.
DeviceParts: add config to disable touchscreen calibrations

Remove the possibility to disable the driver filter to make all
the option visible without scrolling. The possibility to
disable the driver filter is no more available.
