usb: usb_bam: complete resume from hsic low power mode before grant cons

This change fixes a race condition in which IPA BAM push data to HSIC BAM
since HSIC consumer resource was granted while the HSIC BAM was not fully
resumed yet from low power mode, therefore accessing the HSIC BAM registers
caused a BAM HRESP IRQ error.

Fix this issue by granting the hsic consumer only after full resume
have been completed.
