[PATCH] IRQ/Platform-MSI:Increase the maximum MSIs the MSI framework can support.

[MaJun]

From: Ma Jun <majun258 at huawei.com>

The current MSI framework can only support 256 platform MSIs.

But on Hisilicon platform, some network related devices has about 500
wired interrupts.

To support these devices, we need a new maximum value more than 256.
