cmd: Convert existing long help messages to the new macro - Generally we just drop the #ifdef CONFIG_SYS_LONGHELP and endif lines and use U_BOOT_LONGHELP to declare the same variable name as before - In a few places, either rename the variable to follow convention or introduce the variable as it was being done inline before.

cmd: pci: Add command to set MPS of all PCIe devices Enable tuning of the PCI Express MPS (Maximum Payload Size) of each device. The Maximum Read Request Size is not altered. The SAFE method uses the largest MPS value supported by all devices in the system for each device. This method is the same algorithm as used by Linux pci=pcie_bus_safe. The PEER2PEER method sets all devices to the minimal (128 byte) MPS, which allows hot plug of devices later that might only support the minimum size, and ensures compatibility of DMA between two devices on the bus.
