[PATCH v3 2/4] arm64: dts: amlogic: t7: Add UART controllers nodes

[Ronald Claveau]

Add device tree nodes for UART B through F (serial at 7a000 to
serial at 82000), completing the UART controller description for the T7
SoC. Each node includes the peripheral clock.

While at it, move the uart_a node to its correct position in the
bus address order (0x78000) to comply with the DT requirement that
nodes be sorted by their reg address. Complete the
uart_a node with its peripheral clock (CLKID_SYS_UART_A) and the
associated clock-names, matching the vendor default clock assignment,
consistent with the other UART nodes.
