According to the docs, the parent clock of SYS-DMAC[01] is the ZS clock
(at 260 MHz), not the HP clock (at 130 MHz).

I know order doesn't really matter, but all other members are sorted by
value, so R8A7790_CLK_SYS_DMAC1 should come before
R8A7790_CLK_SYS_DMAC0.

"sys-dmac0", "sys-dmac1" (and order changes, cfr. my comment above),
to match the documentation?
