[PATCH v9 12/12] ARM: dts: zte: Declare zx297520v3 CRM device nodes

[Stefan Dösinger]

This makes use of the driver added in the previous patches. It wires up
the uart clocks and resets and allows getting rid of the placeholder
uartclk node.

---

Version 9:
Sort new nodes by mmio address
rename syscon-reboot to "reboot"
adjust to changes in bindings

Version 7:
Add phy nodes to topcrm
Remove syscon from matrixclk again
Adapt remove now-removed extra clk inputs from matrix
Add reset to LSP
osc26m -> clock-26m for the fixed rate clocks, likewise for 32k

Version 6:
Add syscon to matrixclk

Version 5:
Re-name from *clk to *crm
Add the syscon-reboot node here because the binding requires it
Re-add accidentally dropped uart2 IRQ
