[U-Boot] [PATCH v3 13/13] ehci-mx5/6: Make board_ehci_hcd_init() optional

["Benoît Thébaudeau" <benoit.thebaudeau@advansee.com>]

A custom board_ehci_hcd_init() may be unneeded, so add a weak default
implementation doing nothing.

By the way, use simple __weak from linux/compiler.h for
board_ehci_hcd_postinit() instead of weak alias with full attribute.

Changes for v2:
 - Use simple __weak from linux/compiler.h instead of __attribute__.
 - Also use __weak instead of __attribute__ for board_ehci_hcd_postinit().
 - Extend to ehci-mx6.c.
Changes for v3: None.
