Subject: [PATCH 007/290] ARM: configs: at91: unselect PIT
Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=09237389b9cefeb3f5e277ad4e35c5ca3b62db42
The PIT is not required anymore to successfully boot and may actually harm
in case preempt-rt is used because the PIT interrupt is shared.
Disable it so the TCB clocksource is used.
