Revert "USB: sam-ba: add driver for Atmel SAM Boot Assistant (SAM-BA)"

This reverts commit 90593899de83a6e6fdea563d058acd2f4334e3f9.

SAM-BA devices identify themselves CDC-ACM devices and should be using
the cdc-acm driver.

Since commit 5b239f0aebd4dd6f85b13decf5e18e86e35d57f0 (USB: cdc-acm: Add pseudo
modem without AT command capabilities) cdc-acm also binds to them.

Note that the Atmel SAM-BA tools expect to use a USB-serial driver and thus
require a symlink from /dev/ttyACMn to some /dev/ttyUSBm (with m < 30) to be
able to select the device. This is simply a UI-issue that should be
fixed by Atmel.

Tested with the SAM-BA 2.10 tools and an Atmel at91sam9260-ek.
