Both UARTs support higher baudrates and are not limited to baudrate 230400.
Only current kernel driver implementation has limitation for both UARTs in
maximal baudrate 230400. This limitation will be removed in next patches.
So remove incorrect information about (hardware) limitation from bindings.
UART1 (standard variant with DT node name 'uart0') has register space
0x12000-0x12018 and not whole size 0x200. So fix also this in example.

Update the device tree binding documentation for the Marvell EBU UART,
in order to allow describing the extended UART IP block, in addition to
the already supported standard UART IP. This requires adding a new
compatible string, the introduction of a clocks property, and extensions
to the interrupts property.

Armada-37xx UART0 registers are 0x200 bytes wide. Right next to them are
the UART1 registers that should not be declared in this node.
Update the example in DT bindings document accordingly.
