[U-Boot] [PATCH 2/6][v4] armv8: lsch3: Use SVR based timer base address detection

[Priyanka Jain]

From: Priyanka Jain <priyanka.jain at nxp.com>

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 personalities

Changes for v2:
 Rename LS2080A_LS2085A_TIMER_ADDR to SYS_FSL_LS2080A_LS2085A_TIMER_ADDR
