Correct #if to #ifdef when the macro can be undefined. Fix bug in AT32UC3 clock initialization: AVR32_CLOCK_PLL_OSC1 should be AVR32_CLOCK_PLL0_OSC1 and AVR32_CLOCK_PLL1_OSC1.

arch/arm/src/up_iternal.h and several ARM Make.defs files: In the original implementation, NOT defined(CONFIG_ARMV7M_CMNVECTOR) was a sufficient test to determine if lazy floating point register saving was being used. But recents changes added common lazy register as well so now that test must be (NOT defined(CONFIG_ARMV7M_CMNVECTOR) || defined(CONFIG_ARMV7M_LAZYFPU)).

All ARMV7-M IRQ setup: Always set the NVIC vector table address. This is needed in cases where the code is running with a bootload and when the code is running from RAM. It is also needed by the logic of up_ramvec_initialize() which gets the vector base address from the NVIC. Suggested by Pavel Pisa

Logic that samples the free running counter reads the pending interrupt status regsiter and can cause interrupts to be lost. So, if when the status regsiter is read, the logic must also handle the timer overflow event. Found and fixed by Max Neklyudov

SAM3/4 and SAMV7 Serial: Serial interrupts left disabled.
...
A side-effect of changing serial settings via TERMIOS (such as tcsetattr) is that serial interrupts were being left disabled. This is not a problem if the serial configuration is changed when there are no open references to the serial device. In that case, serial interrupts are disabled and will not be enabled enabled until the serial device is first opened. But it is fatal if the serial device is already opened and if there is a task waiting to receive data. In that case, the side-effect of disabling interrupts is fatal: That task is then left hanging with interrupts disabled.
