[PATCH 2/2] clk: spacemit: k3: set rcpu clock as critical

[Yixun Lan]

The SpacemiT K3 SoC integrates two RT24 RISC-V little cores (os0_rcpu and
os1_rcpu), each running an independent ESOS instance responsible for
system power management and real-time task. The RCPU clock is required
in order to keep these cores functional, so set its clock as critical to
prevent it from being shut off.
