With current FDT support driver tries to parse device node twice in ehci_hcd_init() and ehci_hcd_stop(), which shouldn't happen ideally. Making provision to store data in a global structure and thereby passing its pointer when needed.

Changes from v3:
- Checking for error return in exynos_usb_parse_dt() and returning there only in case of failure for DT systems.
- Removed unnecesassry parentheses.
Changes from v2:
- Using hcd as "struct ehci_hccr *" rather than "unsigned int" to avoid unnecessary typecasting later in the code.
- Further using local variable of type "fdt_addr_t" in exynos_usb_parse_dt() and modifying the code as required.
Changes from v1:
- Added patch to fix problem of multiple FDT decode.
