Change vApplicationIRQHandlerConst to 64-bit align

Browse source 
When MMU is disabled, all memory is device type and access should be
aligned. For following code, ullPortInterruptNestingConst should be
64bit aligned. Otherwise, it will crash,

    /* Increment the interrupt nesting counter. */
    LDR         X5, ullPortInterruptNestingConst
    LDR         X1, [X5]        /* Old nesting count in X1. */

However, ullPortInterruptNestingConst is defined after word (32bit)
aligned vApplicationIRQHandlerConst, which causes
ullPortInterruptNestingConstit is also 32bit aligned,

    vApplicationIRQHandlerConst: .word vApplicationIRQHandler
    ullPortInterruptNestingConst: .dword ullPortInterruptNesting

This patch define vApplicationIRQHandler as dword to solve this issue.
