    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()`.
