[PATCH v1 1/1] mfd: ipaq-micro: Use %*ph for printing hexdump of a small buffer

[Andy Shevchenko]

The kernel already has a helper to print a hexdump of a small
buffer via pointer extension. Use that instead of open coded
variant.

In long term it helps to kill pr_cont() or at least narrow down
its use.
