FDT_ERROR is defined as unsigned long. However, since the return value of
fdt_offset() is int, a warning will occur when compiling. Also, it is better
to use -EINVAL than FDT_ERROR.
This fixes this problem by change return value from FDT_ERROR to -EINVAL.

Maximum Data Transfer Size (MDTS) field indicates the maximum
data transfer size between the host and the controller. The
host should not submit a command that exceeds this transfer
size. The value is in units of the minimum memory page size
and is reported as a power of two (2^n).
The spec also says: a value of 0h indicates no restrictions
on transfer size. On the real NVMe card this is normally not
0 due to hardware restrictions, but with QEMU emulated NVMe
device it reports as 0. In nvme_blk_read/write() below we
have the following algorithm for maximum number of logic
blocks per transfer:
u16 lbas = 1 << (dev->max_transfer_shift - ns->lba_shift);
dev->max_transfer_shift being 0 will for sure cause lbas to
overflow. Let's use 20. With this fix, the NVMe driver works
on QEMU emulated NVMe device.

NVM Express (NVMe) is a register level interface that allows host
software to communicate with a non-volatile memory subsystem. This
interface is optimized for enterprise and client solid state drives,
typically attached to the PCI express interface.
This adds a U-Boot driver support of devices that follow the NVMe
standard [1] and supports basic read/write operations.
Tested with a 400GB Intel SSD 750 series NVMe card with controller
