Subject: [PATCH 4.19 189/639] ntb_hw_switchtec: NT req id mapping table register entry number should be 512

From: Wesley Sheng <wesley.sheng@...rochip.com>

[ Upstream commit d123fab71f63aae129aebe052664fda73131921a ]

The number of available NT req id mapping table entries per NTB control
register is 512. The driver mistakenly limits the number to 256.

Fix the array size of NT req id mapping table.

Fixes: c082b04c9d40 ("NTB: switchtec: Add NTB hardware register definitions")
