USB: host: Introduce flag to enable use of 64-bit dma_mask for ehci-platform

Browse Source 
ehci-octeon driver used a 64-bit dma_mask. With removal of ehci-octeon
and usage of ehci-platform ehci dma_mask is now limited to 32 bits
(coerced in ehci_platform_probe).

Provide a flag in ehci platform data to allow use of 64 bits for
dma_mask.
