Set IVPR to kenrel entry point in second core boot page
Assuming the OSes exception vectors start from the base of kernel address, and the kernel physical starting address can be relocated to an non-zero address. This patch enables the second core to have a valid IVPR for debugger before kernel setting IVPR in CAMP mode. Otherwise, IVPR is 0x0 and it is not a valid value for second core which runs kernel at different physical address other than 0x0. Signed-off-by: Haiying Wang <Haiying.Wang@freescale.com>
