Enable PCIe/NVMe support on Data Modul i.MX8M Mini eDM SBC. Except for the configuration options which are enabled, add slight adjustment to board u-boot.dtsi, which is necessary as there is currently no driver for the I2C PCIe clock generator. Since the generator is strapped to be always on, it is possible to supplant the generator functionality by fixed-clock. Signed-off-by: Marek Vasut <marex@denx.de>
