Kishon Vijay Abraham I 5738327c02 PCI: keystone: Add workaround for Errata #i2037 (AM65x SR 1.0)
[ Upstream commit 86f271f22bbb6391410a07e08d6ca3757fda01fa ]

Errata #i2037 in AM65x/DRA80xM Processors Silicon Revision 1.0
(SPRZ452D_July 2018_Revised December 2019 [1]) mentions when an
inbound PCIe TLP spans more than two internal AXI 128-byte bursts,
the bus may corrupt the packet payload and the corrupt data may
cause associated applications or the processor to hang.

The workaround for Errata #i2037 is to limit the maximum read
request size and maximum payload size to 128 bytes. Add workaround
for Errata #i2037 here.

The errata and workaround is applicable only to AM65x SR 1.0 and
later versions of the silicon will have this fixed.
