clk: meson: g12a: Add missing NNA source clocks for g12b

This adds the Neural Network Accelerator source clocks for g12b.

Initial support for sm1 already exist in
commit 0d02a1b9040b
("clk: meson: g12a: Add support for NNA CLK source clocks")

The sm1 and g12b share the same NNA source clocks.
This patch add missing NNA clocks for A311D (g12b).
