[U-Boot] [PATCH 2/6][v3] armv8: lsch3: Use SVR based timer base address detection

Timer controller base address has been changed from
LS2080A SoC (and its personalities) to new SoCs like
LS2088A, LS1088A.
Use SVR based timer base address detection to avoid compile time #ifdef.

Changes for v3:
Update check to svr_dev_id check for LS2080A SoC and its personalties
Changes for v2:
Rename LS2080A_LS2085A_TIMER_ADDR to SYS_FSL_LS2080A_LS2085A_TIMER_ADDR
