net: atlantic: Fix DMA mapping for PTP hwts ring

[ Upstream commit 2e7d3b67630dfd8f178c41fa2217aa00e79a5887 ]

Function aq_ring_hwts_rx_alloc() maps extra AQ_CFG_RXDS_DEF bytes
for PTP HWTS ring but then generic aq_ring_free() does not take this
into account.
Create and use a specific function to free HWTS ring to fix this
issue.
