ARC: [plat-axs103]: Set initial core pll output frequency

Browse Source 
Set initial core pll output frequency specified in device tree to
100MHz for SMP configuration and 90MHz for UP configuration.
It will be applied at the core pll driver probing.

Update platform quirk for decreasing core frequency for quad core
configuration.
