ARM: dts: lpc32xx: Add missing DMA properties

Add properties declared in the new DT binding nxp,lpc3220-dmamux.yaml
and corresponding phandles.

[vzapolskiy]:
1. rebased the change,
2. dmamux unit address shall be 0x78 instead of 0x7c,
3. removed unsupported 'dmas' properties from sd, ssp0, ssp1 and HS UARTs,
4. more non-functional updates by reordering properies,
5. minor updates to the commit message.
