Signal handlers maybe run with interrupts enabled or disabled, depending on how the task the received the signal was blocked. (i.e.: If sem_wait() is called, then we disable interrupts, then block the currently running task). This could be dangerous, because user code would be running with interrupts disabled.
This change forces interrupts to be enabled in up_sigdeliver() before executing the signal handler calling up_irq_enable() explicitly. This is safe because, when we return to normal execution, interrupts will be restored to their previous state when the signal handler returns.

Squashed commit of the following:
arch/arm/src/stm32/stm32f10xxf30xx_flash.c: Re-implemented Dmitriy Linikov's change to support multi-banked FLASH on the STM32 F1 parts AFTER separating the FLASH support by architecture and implementing more standard base+offset register addressing. Now the change goes in rather cleanly.
arch/arm/src/stm32/stm32f10xxf30xx_flash.c: Use base + offset address to simplify implementation of dual bank flash.
Squashed commit of the following:
arch/arm/src/stm32/stm32f10xxf30xx_flash.c: Be consistent in file naming.
arch/arm/src/stm32l10xxf30xxx_flash.c: Separate STM32F10xx and STM32F30xx FLASH logic into a separate file.
arch/arm/src/stm32l20xx40xxx_flash.c: Separate STM32F20xx and STM32F40xxFLASH logic into a separate file.
arch/arm/src/stm32l15xx_flash.c: Separate STM32L15xx FLASH logic into a separate file.
Kinetis UART must be placed in 9 bit mode (M=1) with when 8 bit
data with parity is required. If left in 8 bit mode (M=0) with
parity then D7 of the TX/RX register becomes parity bit. Hence
what is called 9-bit or 8-bit Mode Select is a misnomer.
8 bit mode when parity is enabled is realy 7 bit with parity.
Previous BRFA was not cleared and or-ed into new BRFA, hence
buadrate was wrong. Where Baud Rate Fractional Divisor (BRFD)
UART baud rate = clock / (16 * (SBR + BRFD))
