coresight: Use %px to print pcsr instead of %p

Browse Source 
[ Upstream commit 831c326fcd ]

Commit ad67b74d24 ("printk: hash addresses printed with %p") lets
printk specifier %p to hash all addresses before printing, this was
resulting in the high 32 bits of pcsr can only output zeros.  So
module cannot completely print pc value and it's pointless for debugging
purpose.

This patch fixes this by using %px to print pcsr instead.
