usb: pci-quirks: Reduce the length of a spinlock section in usb_amd_find_chipset_info()
[ Upstream commit c03ff66dc0e0cbad9ed0c29500843e1da8533118 ]
'info' is local to the function. There is no need to zeroing it within
a spin_lock section. Moreover, there is no need to explicitly initialize
the .need_pll_quirk field.
Initialize the structure when defined and remove the now useless memset().
