The names of all fclk divider gate clocks follow the naming schema
"fclk_divN" and the name of all fclk fixed dividers follow the naming
schema "fclk_divN_div".
There's one exception to this rule: meson8b_fclk_div3_div's name is
"fclk_div_div3". It's child clock meson8b_fclk_div3 however references
it as "fclk_div3_div" (following the naming schema explained above).

Fix the naming of the meson8b_fclk_div3_div clock to follow the naming
schema. This also fixes serial console on my Meson8m2 board because
"clk81" uses fclk_div3 as parent. However, since the hierarchy stops at
meson8b_fclk_div3 there's no known parent clock and the rate of "clk81"
and all of it's children (UART clock, SDIO MMC controller clock, ...)
are all 0.

Oopss ... Thanks for fixing this Martin.

Stephen, Do you mind taking this directly for fixes ? I can prepare a PR if you
prefer.

Nevermind, apparently I have another mistake of the same kind, so there is
another fix coming up.

I'ĺl make a PR
