HACK: cpufreq: ti-cpufreq: extend am625 efuse table

commit 2580d89e9f9914f66f36f73536ffa22d35036324 from
git://git.ti.com/ti-linux-kernel/ti-linux-kernel.git



The am62a7 and am62p5 have more letters than the typical G,K,S, and T
speed grades. While we work to understand how to support these extended
speed grade tables, append U, and V to T to allow cpufreq to scale to
the 1.25/1.4GHz for am62a7 and am62p5.

I've labeled this as a HACK mainly because these will probably need to
become separate tables for each SoC (the am62a7 especially) when adding
support upstream as not all the speed at each letter aligns between SoCs
