The RK3588 Theobroma boards (Tiger and Jaguar) need a different reset mode for the PMIC to work properly, c.f. DT patches in this series.
While the kernel just recently (v6.17-rc1) gained support for setting this appropriately, all upstream kernels before that release will simply not behave appropriately for those boards. While it is typically much easier to update the Linux kernel than U-Boot, let's cover all possible scenario by adding support for setting this reset mode properly from U-Boot so that there isn't a need for patching or updating the kernel.
