any particular reason for diverging from namings set in the other binding
headers (PLL_APLL, ARMCLK, ...)?

the rk1108 seems to have a pretty small clock tree, so maybe you can reduce
the gap here a bit, like starting at 128 or 192 for the ACLKs and move
everything up a bit?

That way you save a bit of space, as we're allocation CLK_NR_CLKS entries or
the lookup array when probing the clock driver.
