The kernel prints a message similar to
"[ 28.881959] do_IRQ: 5.36 No irq handler for vector"
when GL975x resumes from suspend. Implement a resume callback to fix this.

Enable MSI interrupt for GL9750/GL9755. Some platforms
do not support PCI INTx and devices can not work without
interrupt. Like messages below:

Add support for the GL9750 and GL9755 chipsets.
Enable v4 mode and wait 5ms after set 1.8V signal enable for GL9750/
GL9755. Fix the value of SDHCI_MAX_CURRENT register and use the vendor
tuning flow for GL9750.
