[PATCH V4 4/7] cpu: imx8_cpu: Print Speed grade if 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 temperature grade and active
temperature are only displayed when SoC is an i.MX9. Since IMX9 now
implies IMX_TMU, change this to check for IMX_TMU in the same way
it's done in mach-imx/cpu.c to enable displaying this information
for any SoC with either of this config enabled.
Since additional text may appear due to this commit, remove
the extra space in the message displaying the temperature
grade.

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
