Use %lx format to print registers. This avoids having two different
formats and avoids checking for MSR_64BIT, improving readability of the
function.
Even though we could have used %px, which is functionally equivalent to %lx
as per Documentation/core-api/printk-formats.rst, it is not semantically
correct because the data printed are not pointers. And using %px requires
casting data to (void *).
Besides that, %lx matches the format used in show_regs().
Before this patch:

0000000010000574 lr 00007fff935e7a6c code 2
After this patch:
