[U-Boot] [PATCH] Set IVPR to kenrel entry point in second core boot page

[Haiying Wang]

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.
