[PATCH] soc: amlogic: clk-measure: Mark the clock measure table as __initconst

From: Jian Hu <[email protected]>

The clock measure table is only used during initialization, and the
table data is copied to the msr_table field of struct meson_msr_data.

Mark it as __initconst so it can be freed after kernel initialization.
Taking T7 as an example, this frees approximately 5 KB of memory,
saving some runtime memory.
