ath79: read back reset register
Read back the reset register in order to flush the cache. This fixes
spurious reboot hangs on TP-Link TL-WDR3600 and TL-WDR4300 with Zentel
DRAM chips.
This issue was fixed in the past, but switching to the reset-driver
specific implementation removed the cache barrier which was previously
implicitly added by reading back the register in question.
