Simon Glass 20e442ab2d dm: Rename U_BOOT_DEVICE() to U_BOOT_DRVINFO()
The current macro is a misnomer since it does not declare a device
directly. Instead, it declares driver_info record which U-Boot uses at
runtime to create a device.

The distinction seems somewhat minor most of the time, but is becomes
quite confusing when we actually want to declare a device, with
of-platdata. We are left trying to distinguish between a device which
isn't actually device, and a device that is (perhaps an 'instance'?)

It seems better to rename this macro to describe what it actually is. The
macros is not widely used, since boards should use devicetree to declare
devices.

Rename it to U_BOOT_DRVINFO(), which indicates clearly that this is
declaring a new driver_info record, not a device.
