Add optional bl1_plat_prepare_exit() API
This patch adds an optional API to the platform port:
void bl1_plat_prepare_exit(void);
This function is called prior to exiting BL1 in response to the
RUN_IMAGE_SMC request raised by BL2. It should be used to perform
platform specific clean up or bookkeeping operations before
transferring control to the next image.
A weak empty definition of this function has been provided to
preserve platform backwards compatibility.
