usb: pci-quirks: Reduce the length of a spinlock section in usb_amd_find_chipset_info() 

[ Upstream commit c03ff66dc0 ]

'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().
