Subject: [PATCH 5/8] usb: phy: msm: reset controller is mandatory now

Commit a27345434134 "usb: phy: msm: Use reset framework for LINK
and PHY resets" introduced a mandatory call to reset_control_get
into the msm usb phy driver, which means we have to add a Kconfig
dependency on the API to avoid this build error:

phy/phy-msm-usb.c: In function 'msm_otg_read_dt':
phy/phy-msm-usb.c:1461:2: error: implicit declaration of function 'devm_reset_control_get' [-Werror=implicit-function-declaration]
  motg->link_rst = devm_reset_control_get(&pdev->dev, "link");
  ^
