911954859d dm: Use dm_scan_fdt_dev() directly where possible
Quite a few places have a bind() method which just calls dm_scan_fdt_dev().
We may as well call dm_scan_fdt_dev() directly. Update the code to do this.

2e3f1ff63f dm: Convert users from dm_scan_fdt_node() to dm_scan_fdt_dev()
This new function is more convenient for callers, and handles pre-relocation
situations automatically.

aafa64827f spmi: Fix sandbox spmi driver memory corruption
There is off-by-one error in sandbox_emul_gpio that causes
segfault of certain tests.

EMUL_GPIO_REG_END is the address of last valid (emulated) register.
This patch fixed this (by adding one more element to emulated register array).

04868b407b drivers: Add SPMI bus uclass
Qualcom processors use proprietary bus to talk with PMIC devices -
SPMI (System Power Management Interface).
On wiring level it is similar to I2C, but on protocol level, it's
multi-master and has simple autodetection capabilities.
This commit adds simple uclass that provides bus read/write interface.
