Before commit 53a2d95df8 ("usb: core: add phy notify connect and
disconnect"), phy initialization will be skipped even when shared hcd
doesn't set skip_phy_initialization flag. However, the situation is
changed after the commit. The hcd.c will initialize phy when add shared
hcd. This behavior is unexpected for some platforms which will handle phy
initialization by themselves. To avoid the issue, this will only check
skip_phy_initialization flag of primary hcd since shared hcd normally
follow primary hcd setting.
