This fixes the following similar build warning when
enabling compile test:

aspeed-hace-hash.c:188:9: warning: format '%x' expects argument of type
'unsigned int', but argument 7 has type 'size_t' {aka 'long unsigned int'}
[-Wformat=]

Reported-by: kernel test robot <lkp@intel.com>
Signed-off-by: Neal Liu <neal_liu@aspeedtech.com>

v2: Use "%zu" format to print size_t.

Shouldn't we use %pad instead of %zu for dma_addr_t (you'll also
need to pass in a dma_addr_t pointer instead of the value)?

That sounds correct.
I only looked at the size_t parts...

True. I'll revise it and send next patch, thanks.
