pmdomain: imx: scu-pd: correct DMA2 channel

pmdomain: imx: scu-pd: correct DMA2 channel

Per "dt-bindings/firmware/imx/rsrc.h", `IMX_SC_R_DMA_2_CH0 + 5` not
equals to IMX_SC_R_DMA_2_CH5, so there should be two entries in
imx8qxp_scu_pd_ranges, otherwise the imx_scu_add_pm_domain may filter
out wrong power domains.

Fixes: 927b7d15dcf2 ("genpd: imx: scu-pd: enlarge PD range")
