Modified the TARGET_GHI_MBUINO/PeripheralNames.h and targets/hal/TARGET_NXP/TARGET_LPC11UXX/TARGET_GHI_MBUINO/PinNames.h to reflect the mBuino base hardware;
I commented out the non useful SPI pins and Serial pins from our hardware build;
For pwmout, I removed the non useful pins and added two more pins that are part of our hardware build.

This reverts commit 6b910f27637f2956bea6bfbeee97610d266937ce.
Removed the Peripheral Pin Definitions from the xxx_api.c files (analogin, i2c, pwmout, serial, & spi) to follow an example from Erik O. from this platform: https://github.com/mbedmicro/mbed/blob/master/libraries/mbed/targets/hal/TARGET_Freescale/TARGET_KLXX/TARGET_KL46Z/PeripheralPins.c to allow for advanced compatibility of platforms;
Subsequently, the Peripheral Pin Definitions were added to the file called PeripheralPins.c to accommodate the removal of the definitions from the main xxx_api.c files and added it to each respective Target folder;
Added PeripheralPin.h to point to the PeripheralPin.c files in the target directories.
Modified the linker script for the ARM Micro, Standard, and GCC to accommodate for the specific chip that the mBuino platform uses LPC11U24FHI33/301 which is 6kB in the SRAM vs 8kB;
Added ('GHI_MBUINO',     ('ARM', 'uARM', 'GCC_ARM')), to the OFFICIAL_MBED_LIBRARY_BUILD section of build_release.py.
The following changes were based on the request by Martin Kojtal:
Removed the pin definition comments from the xxx_api.c files;
Added GHI_MBUINO to the build_travis.py target section.
