Subject: [PATCH v3] xHCI: Fixing xhci_readl definition and function call
This patch redefine function xhci_readl.xhci_readl function doesn't use xhci_hcd argument.
Hence there is no need of keeping it in the function arguments.
Redefining this function breaks other functions which calls this function.
This phatch also correct those calls in xhci driver.
