[ Upstream commit 551a60e1225e71fff8efd9390204c505b0870e0f ] The iMSI-RX module of the DW PCIe controller provides multiple sets of MSI_CTRL_INT_i_* registers, and each set is capable of handling 32 MSI interrupts. However, the fu740 PCIe controller driver only enabled one set of MSI_CTRL_INT_i_* registers, as the total number of supported interrupts was not specified. Set the supported number of MSI vectors to enable all the MSI_CTRL_INT_i_* registers on the fu740 PCIe core, allowing the system to fully utilize the available MSI interrupts.
