SMMUv3 driver functions which are called from BL1 and BL31 currently use counter-based poll method for testing status bits. Adding Delay Timer driver to BL1 and BL31 is required for timeout-based implementation using timer delay functions for SMMU and other drivers. This patch adds new function `fvp_timer_init()` which initialises either System level generic or SP804 timer based on FVP_USE_SP804_TIMER build flag. In BL2U `bl2u_early_platform_setup()` function the call to `arm_bl2u_early_platform_setup()` (which calls `generic_delay_timer_init()` ignoring FVP_USE_SP804_TIMER flag), is replaced with `arm_console_boot_init()` and `fvp_timer_init()`.
