Fix Bob's name in as many places as possible; Make sure that Bob is an author in as many files as I can think of (might be missing a few)

Various SAM4S related fixes, mostely related to the timer driver driver and the SAM4S timer/counter.  All from Bob Doisin

LPC17xx:  Prioritized interrupts are not supported (although hooks are present to prioritize interrupts).  Make LPC17 Ethernet default priority to be the system default, not the highest.  If the unsupported feature is enabled, then at least it should do no harm

LPC17xx, TIVA, and Kinetis interrupt initialization:  use the NVIC ICTR register to determine how many interrupt lines/registers are supported by the MCU

Move the un-definitions of __ramfuncs__ from the sam_clockconfig.c to the common up_internal.h header file so that the attribute will be applied the same to function definitions and prototypes.

SAMA5 TWI: If running from SDRAM, BOARD_MCK_FREQUENCY is not a constant and cannot be used in pre-processor conditionals

SAMA5 SSC: If running from SDRAM, BOARD_MCK_FREQUENCY is not a constant and cannot be used in pre-processor conditionals

SAMA5 EMAC/GMAC: If running from SDRAM, BOARD_MCK_FREQUENCY is not a constant and cannot be used in pre-processor conditionals

SAMA5 CAN: If running from SDRAM, BOARD_MCK_FREQUENCY is not a constant and cannot be used in pre-processor conditionals

SAMA5 ADC: If running from SDRAM, BOARD_MCK_FREQUENCY is not a constant and cannot be used in pre-processor conditionals

SAMA5: The PIO used for the red LED is also used as the camera module reset line:  Added a configuration option to suppress use of the red LED if the PIO is used for another purpose.  Reported by David Sidrane.

Add some checks:  if getpid() or get_errno_ptr() are called very early in the initialization sequence, they would fail

configs/*/defconfig: Increase the number of pre-allocated watchdogs in configurations that use networking or USB

Back out part of  610e2aa0c224e2936fe8009ef4a2351ce607067a: Need to be able to select USB console devices when there is no /dev/console enabled.  Noted by Librae

Add logic for TM4C125GXL clocking based on prototype from from Daniel Carvalho with modifications. I think the LM4F120 may have broken before as well(?).  In any event, the LM4F120 also works well with this chanage
