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.

The R-Car Gen2 feeds the TMU with CONFIG_SYS_CLK_FREQ / 2,

These functions are always called for timer = 0, so drop the
