That is correct, I can include it on HK01 which has an SDHCI controller
and thus can consume L11 for VQMMC so that HS200 and higher work.

I wanted to include the nodes directly in the SoC DTSI and set L11 as VQMMC
for SDHCI there as this is a companion PMIC and always present, but
the established
procedure is for the PMIC to have its own DTSI and then be included per board.
