If the drive-strength isn't specified in the device tree then it
doesn't actually default to 2. Instead, it defaults to whatever the
heck the BIOS left it at. If the BIOS doesn't touch it then that means
it's whatever the heck the initial state of the pin was when the SoC
booted.

Several properties are shared between all TLMM bindings. By providing a
common binding to define these properties each platform's binding can be
reduced to just listing which of these properties should be checked for
- or further specified.
