board: nucleo-l152re: Add missing I2C1 GPIO definition
I2C1 not worked due to it's GPIO pin definition has been missing on board.h.
Fix it through include two pin macros on stm32l15xxx_pinmap.h(arch/arm/src/stm32/hardware) to board.h
GPIO_I2C1_SCL => PB8 (CN5 pin 10, D15)
GPIO_I2C1_SDA => PB9 (CN5 pin 9, D14)

Added board_late_initialize() function for init I2C.

board: nucleo-l152re: Added registering logic I2C on /dev.
I2C1 hasn't been registered on /dev. Fix it.

board: nucleo-l152re: Fix code style.

Update board.h

board: nucleo-l152re: Fix code style.

Variables starting with symbol '"g_*" means it is a global variable, I think this is not the case here.

Fix code style

* Name: board_late_initialize

* Description:
* If CONFIG_BOARD_LATE_INITIALIZE is selected, then an additional
* initialization call will be performed in the boot-up sequence to a
* function called board_late_initialize(). board_late_initialize() will be
* called immediately after up_initialize() is called and just before the
* initial application is started. This additional initialization phase
* may be used, for example, to initialize board-specific device drivers.
