board: Rename uclass to sysinfo This uclass is intended to provide a way to obtain information about a U-Boot board. But the concept of a U-Boot 'board' is the whole system, not just one circuit board, meaning that 'board' is something of a misnomer for this uclass. In addition, the name 'board' is a bit overused in U-Boot and we want to use the same uclass to provide SMBIOS information. The obvious name is 'system' but that is so vague as to be meaningless. Use 'sysinfo' instead, since this uclass is aimed at providing information on the system. Rename everything accordingly. Note: Due to the patch delta caused by the symbol renames, this patch shows some renamed files as being deleted in one place and created in another.

menuconfig SYSINFO
bool "Device System Information"
drivers: Add board uclass Since there is no canonical "board device" that can be used in board files, it is difficult to use DM function for board initialization in these cases. Hence, add a uclass that implements a simple "board device", which can hold devices not suitable anywhere else in the device tree, and is also able to read encoded information, e.g. hard-wired GPIOs on a GPIO expander, read-only memory ICs, etc. that carry information about the hardware. The devices of this uclass expose methods to read generic data types (integers, strings, booleans) to encode the information provided by the hardware.

Support methods to query hardware configurations from internal
mechanisms (e.g. reading GPIO values, determining the presence of
devices on busses, etc.). This enables the usage of U-Boot with
modular board architectures.
