aspeed/soc: Support Timer for AST2700
Add Timer model for AST2700 Timer support. The Timer controller include 8 sets
of 32-bit decrement counters.
The base address of TIMER0 to TIMER7 as following.
Base Address of Timer 0 = 0x12C1_0000
Base Address of Timer 1 = 0x12C1_0040
Base Address of Timer 2 = 0x12C1_0080
Base Address of Timer 3 = 0x12C1_00C0
Base Address of Timer 4 = 0x12C1_0100
Base Address of Timer 5 = 0x12C1_0140
Base Address of Timer 6 = 0x12C1_0180
Base Address of Timer 7 = 0x12C1_01C0
The interrupt of TIMER0 to TIMER7 as following.
GICINT16 = TIMER 0 interrupt
GICINT17 = TIMER 1 interrupt
GICINT18 = TIMER 2 interrupt
GICINT19 = TIMER 3 interrupt
GICINT20 = TIMER 4 interrupt
GICINT21 = TIMER 5 interrupt
GICINT22 = TIMER 6 interrupt
GICINT23 = TIMER 7 interrupt
