Add initial device trees for the RTD1295 SoC and the Zidoo X9S TV box. The CPUs lack the enable-method property because the vendor device tree uses a custom "rtk-spin-table" method and "psci" did not appear to work. The UARTs lack the interrupts properties because the vendor device tree connects them to a custom interrupt controller. earlycon works without. A list of memory reservations is adopted from v1.2.11 vendor device tree: 0x02200000 can be used for an initrd, 0x01b00000 is audio-related; ion-related 0x02600000, 0x02c00000 and 0x11000000 are left out; 0x10000000 is used for sharing the U-Boot environment; others remain to be investigated.
