USB: EHCI: don't allocate hardware periodic table atomically by default
ehci_mem_init() is executed one time during ehci_init() and by default
all memory allocations but ehci->periodic are done not atomically,
GFP_KERNEL is passed as flags parameter.
Do similar allocation for ehci->periodic and free some space in
coherent atomic DMA pool by default.
