MLK-18127 ARM: dts: imx7ulp-evk: few correction for usdhc1

Currently, WiFi only work on SDIO2.0 mode, so add property
"no-1-8-v", otherwise following warning log will be print

sdhci-esdhc-imx 40380000.usdhc: could not get ultra high speed state, work on normal mode

The regulator reg_vsd_3v3 and reg_sd1_vmmc has the same
regulator name, so will trigger the following error log:

VSD_3V3: Failed to create debugfs directory

So change the regulator name of reg_sd1_vmmc.

According to the spec suggestion, ibe need to be enabled
for usdhc clock pin, and clock is better to pull down.
