[PATCH 1/4] cpu: imx8_cpu: Print Speed grade if IMX_THERMAL or IMX_TMU

[Adam Ford <aford173@gmail.com>]

Much of the data that is display by imx8_cpu.c is also
displayed from arch/arm/mach-imx/cpu.c, except the
speed grade and temperature unless the SoC is an i.MX9.
Expand this to include checks for IMX_THERMAL or IMX_TMU
in the same way it's done for mach-imx/cpu.c.

Before:
CPU:   NXP i.MX8MP Rev1.1 A53 at 1200 MHz
Model: Beacon EmbeddedWorks i.MX8MPlus Development kit

After:
CPU:   NXP i.MX8MP Rev1.1 A53 at 1200 MHz
CPU:   Industrial temperature grade  (-40C to 105C) at 28C
Model: Beacon EmbeddedWorks i.MX8MPlus Development kit
