According to the internal document "Hardware interfaces
standardization", the UART interfaces should be accessed
via device nodes named with the module family and matching
the signal name used in the module datasheet.
Modify udev rules for UART devices accordingly.

There are 2 different names for spi use by downstream and upstream
kernel. Fix the udev rules to match both variants.

This commit adds rules to udev so apalis/colibri or verdin spi
devices are symlinked consistently.

These rules make sure that a symlink is created for all i2c and tty
devices. This symlinks are named like on the Toradex carrier boards.
This makes it easy to identify which device in software is matching
the hardware pins.
Additional non-standard devices that are not named clearly on the
carrier board are left out to prevent confusion.

These machines use an old Nvidia provided downstream kernel 3.1.10. They no
longer much the way more recent sysroot components, e.g. libc, xserver et. al.
The maintance burden to keep the userspace components in their old version
becomes simply to high. Keep using the rocko based 2.8 BSP for these machines.

Configure the read_ahead cache size to optimal value, for the
mmcblk devices (eMMC and SD card).
The cache values are module specific, tests were run on the pre-built
image (BSP V2.7 Beta 1). The measurement of read speed for a range of
cache sizes (16kB to 256MB) was made using hdparm -t.

oe-core moved the mountpoint used to /run/media/<drive>.
In our setup we don't see issues with /media being read only
when udev starts mounting.
In our environment with graphical desktop udisks will later take over
the automount job and udisks currently still uses /media,
so keep this consistent between mounting at boottime and mounting at runtime.
