[PATCH] remoteproc: k3-r5: Fix rproc init failure for Main R5FSS0

[Suman Anna]

The Main R5FSS0 cluster is also enabled to probe the R5F remoteproc
driver within R5 SPL for booting the Core0 very early. This results
in a ti_sci_power_domain_on failure during the probe from the A72
U-Boot when "rproc init" is executed at U-Boot prompt, and doesn't
enumerate all the rproc devices.

Fix this by suppressing the power_domain_on altogether using the
flag DM_FLAG_DEFAULT_PD_CTRL_OFF added in commit af94ad418dc7
("dm: core: Allow for not controlling the power-domain by DM framework").

Hi Lokesh,

The recently staged R5 SPL remoteproc boot support causes the rproc init
command to fail on U-Boot prompt. This is a fix for the same. Patch is
against ti/next branch.

regards
Suman
