[U-Boot] [PATCH 1/9] ioport.h: Remove struct resource & co

[Paul Burton]

We only use struct resource in a single place (drivers/usb/dwc3/core.h)
for a field (xhci_resources) which is never used. Only ARM currently
defines resource_size_t which means linux/ioport.h only compiles there.
In preparation for making use of the IORESOURCE_ flags, remove struct
resource & the various declarations of functions which we don't
implement.
