Revert "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;"

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.
