Henrik Brix Andersen c41dd36de2 drivers: kconfig: unify menuconfig title strings
Unify the drivers/*/Kconfig menuconfig title strings to the format
"<class> [(acronym)] [bus] drivers".

Including both the full name of the driver class and an acronym makes
menuconfig more user friendly as some of the acronyms are less well-known
than others. It also improves Kconfig search, both via menuconfig and via
the generated Kconfig documentation.

Patryk Duda f7fca220ba drivers: bbram: Introduce BBRAM shell
Add 'bbram' command which is very convenient tool for examining and
modyfying BBRAM content.

Examples:

Write one byte:
$ bbram write backup_regs 0x1 0xaa

Write many bytes (starting from 0x13):
$ bbram write backup_regs 0x13 0xa 0xb 0xc 0xd 0xe 0xf 0xaa 0xab 0xac

Read whole BBRAM:
$ bbram read backup_regs

Read many bytes (4 bytes starting from address 0x14 in this case):
$ bbram read backup_regs 0x14 4

Read one byte (from 0x14 address):
$ bbram read backup_regs 0x14

Patryk Duda e02456a52d drivers: bbram: Introduce STM32 BBRAM driver
STM32 battery-backed RAM is organized in 4 byte registers. Number of
registers can vary between models from 5 to 32 registers.

Usually, the registers are part of RTC. On some variants they are part
of tamper module. On STM32F1 the registers are in separate module. For
now, only backup registers from RTC are supported.

Yuval Peress 74b9a607b4 drivers: bbram: Add it8xxx2 BBRAM driver implementation
Note that the it8xxx2 does not support a status register so that
functionality is omitted.

This change also adds driver tests that build both the npcx and it8xxx2
drivers.
