dt-bindings: clock: amlogic: t7: Add missing mpll3 parent clock

Browse Source 
The mpll3 clock is one parent clock of the sd_emmc and mipi_isp clocks
on the Amlogic T7 SoC, but was missing from t7-peripherals-clkc.yaml
bindings. Add the mpll3 clock source to the T7 peripherals clock
controller input clock list, so that sd_emmc and mipi_isp can use it.

For logical consistency, place the required mpll3 entry before the
optional entry.

This change breaks the ABI, but while the amlogic,t7-peripherals-clkc
bindings have been merged upstream, the corresponding DT has not been
merged yet. Thus, no real users or systems are affected.
