Subject: apm821xx: remove broken PCIe MSI support
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0e841fd4a229e974a573b5e79d2f0e6247275b15;p=openwrt%2Fstaging%2Fthess.git

apm821xx: remove broken PCIe MSI support

These never worked and upstream is in the process of removing
them as well. Legacy PCI interrupt signaling is still working
as before.
