coresight: type cast 32-bit physical address to phys_addr_t 

TMC_ETR_SG_ENT_TO_BLK macro performs bit manipulations on the entry in
scatter gather table for TMC-ETR DDR configuration to convert it to
physical address pointing to 4K blocks of physical memory.

On 64-bit architecture, the top 32-bits are lost if 32-bit address is
passed to this macro and value becomes 64-bit after bit manipulation. Type
cast 32-bit physical address to phys_addr_t when passing to
TMC_ETR_SG_ENT_TO_BLK macro.
