commit 30a90f56c3a2 ("dm: core: add functions to get memory-mapped I/O

All Linux firmware drivers are put under "/firmware" node
and it has support to populate "/firmware" node by default.
u-boot and Linux can share same DTB. In this case, driver
probe for devices under "/firmware" will not be invoked
as "/firmware" does not have its own "compatible" property.
This patch scans "/firmware" node by default like "/clocks".

Create separate function for scanning node by path and
move "/clock" node scan code into that function.
This will be usable if scanning of more node is required.

When the DM CPU drivers are active, printing information about a CPU
should be delegated to a matching driver.
Hence, add a static print_cpuinfo that implements this delegation when
DM CPU drivers are active.

To print the reset status during boot, add a method print_resetinfo to
board_f, which is called in init_sequence_f[], that gets the reset
information from the sysreset driver (assuming there is only one seems
reasonable), and prints it.

It's useful to have the reset status of the SoC printed out during reset
(e.g. to learn whether the reset was caused by software or a watchdog).
As a first step to implement this, add a get_status method to the
sysreset class, which enables the caller to get printable information
about the reset status (akin to get_desc in the CPU uclass).

Sandbox is not a real bootloader and it does require
a position independent code to be supported.
Thus, build it with -fPIC explicitly.
