net: macb: remove #if defined(CONFIG_ARCH_AT91) sections

Browse Source 
With multi platform support those sections could lead to unexpected
behavior if both ARCH_AT91 and another ARM SoC using the MACB IP are
selected.
Add two new capabilities to encode the default MII mode and the presence
of a CLKEN bit in USRIO register.
Then define the appropriate config for IPs embedded in at91 SoCs.
