arc: axs103_smp: Fix CPU frequency to 100MHz for dual-core
The most recent release of AXS103 [v1.1] is proven to work
at 100 MHz in dual-core mode so this change uses mentioned feature.
For that we:
* Update axc003_idu.dtsi with mention of really-used CPU clock freq
* Remove clock override in AXS platform code for dual-core HW
Note we're still leaving a hack for clock "downgrade" on early boot
for quad-core hardware.
Also note this change will break functionality of AXS103 v1.0 hardware.
That means all users of AXS103 __must__ upgrade their boards with the
most recent firmware.
