[RESEND PATCH v4 1/5] clocksource: move some enums and marcos to header file for arm_arch_timer

[fu . wei]

From: Fu Wei <fu.wei@xxxxxxxxxx>

The patch sorts out the code for arm_arch_timer:
    (1)move enum ppi_nr to the header file
    (2)move "ARCH_*_TIMER" marcos to the header file
    (3)add enum spi_nr in the header file, and use it in the driver
    (4)add ARCH_WD_TIMER and ARCH_TIMER_MEM_MAX_FRAME marcos
