Add the Low Power Timer/Pulse Width Modulation Module 6 (TPM6)
node to the i.MX 7ULP device tree.
TPM6 is located in the Application Domain (Cortex-A7) at base
address 0x40a10000. This enables PWM and timer support for
peripherals connected to this domain, such as display backlight
controllers.

Please slow down and avoid post new patch in old thread, which will confuse
patchwork or other tools.
