[PATCH v2] ARM: dts: imx7ulp: Add TMP6 PWM node to i.MX7ULP

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.

v2:
 - Move tpm6 node under ahbbridge1 (bus at 40800000), before lpi2c6 at 40a40000
   (reported by DT bot)
 - Fix author/Signed-off-by email typo (simpthicode -> sympthicode)
