Selecting this option will pass "-Map=$(TOPDIR)$(DELIM)nuttx.map" to ld
when linking NuttX ELF. That file can be useful for verifying
and debugging magic section games, and for seeing which
pieces of code get eliminated with DEBUG_OPT_UNUSED_SECTIONS.

Enable this option to optimization the unused input sections with the
linker by compiling with " -ffunction-sections -fdata-sections ", and
linking with " --gc-sections ".

arm/armv7-[a|r]: move fpu save/restore to assembly handler
Save/Restore FPU registers in C environment is dangerous practive,
which cannot guarantee the compiler won't generate the assembly code
with float point registers, especially in interrupt handling

## Summary
A lot of linker scripts were listed twice, once for unix, once for windows.
This PR cleans up the logic so they're only listed once.
## Impact
Any opportunity to use a single source of truth and reduce lines of code is a win!
## Testing
CI will test all build
State of problem:
- Some drivers that do not support write operations (does not
have write handler or ioctl do not perform any write actions)
are registered with write permissions
- Some drivers that do not support read operation (does not
have read handler or ioctl do not perform any read actions)
are registered with read permissions
- Some drivers are registered with execute permissions
Solution:
- Iterate code where register_driver() is used and change 'mode'
parameter to reflect the actual read/write operations executed
by a driver
- Remove execute permissions from 'mode' parameter

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.

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
