OPAMP support for STM32F33XX

Signed-off-by: Juha Niskanen <juha.niskanen@haltian.com>

binfmt: Fix offset value when calling elf_read() in elf_sectname()

Approved-by: Gregory Nutt <gnutt@nuttx.org>

pthread: Fix compilation error on pthread_cond_wait when CONFIG_CANCELLATION_POINTS and CONFIG_PTHREAD_MUTEX_UNSAFE are enabled.

EFM32, STM32, and STM32 F7 I2C:  Update to use the standard parameter passing to interrupt handlers.

STM32F0: Add some protection.  There is only one interrupt for USART3-8.  Current interrupt handling logic will support only one interrupt in that range.

I am not sure why spi.h is still generating warnings.  A few more parentheses and that seems to fix the problem
