Pull request for cortex-r4 codes
* arm/armv7-r: Add general interrupt controller.
This is based on armv7-a gic controller code.

* arm/armv7-r: add invalidate dcache in arm_head.S
Adding invalidate dcache as a comment in arm_head.S.

* arm/armv7-r: Fix some wrong configuration of program status register.
PSR_E_BIT bit should be set for big endian system.
PSR_A_BIT bis is set automatically as arm cortex-r4 reference manual 3.7.4.
So we don't need to set this bit.

* arm/armv7-r: Fix some wrong MPU register definition.
Change MPU_RBAR_ADDR_MASK and MPU_RACR_TEX_SHIFT mask as
arm cortex-r4 reference manual.
Region Base Address Register 0-4 bits are reserved.
MPU Region Access control register type 3-5 bits.

drivers/mtd: mtd_config.c: Add still more error handling (to detect bad underlying flash implementations)
drivers/mtd: mtd_config.c: Remove MTD_ERASE that was erasing data block instead of erase block. This is a partial revert of 4f18b4. Reported-by: Pascal Speck <iktek01@yahoo.com>
arch/arm/src/stm32l4: stm32l4_flash: change flash programming to use page buffer for unaligned writes.
Squashed commit of the following:
Change all calls to usleep() in the OS proper to calls to nxsig_usleep()
sched/signal: Add a new OS internal function nxsig_usleep() that is functionally equivalent to usleep() but does not cause a cancellaption point and does not modify the errno variable.
sched/signal: Add a new OS internal function nxsig_sleep() that is functionally equivalent to sleep() but does not cause a cancellaption point.
This commit backs out most of commit b4747286b1. That change was added because sem_wait() would sometimes cause cancellation points inappropriated. But with these recent changes, nxsem_wait() is used instead and it is not a cancellation point.
In the OS, all calls to sem_wait() changed to nxsem_wait(). nxsem_wait() does not return errors via errno so each place where nxsem_wait() is now called must not examine the errno variable.
In all OS functions (not libraries), change sem_wait() to nxsem_wait(). This will prevent the OS from creating bogus cancellation points and from modifying the per-task errno variable.
sched/semaphore: Add the function nxsem_wait(). This is a new internal OS interface. It is functionally equivalent to sem_wait() except that (1) it is not a cancellation point, and (2) it does not set the per-thread errno value on return.
sched/semaphore: Add nxsem_post() which is identical to sem_post() except that it never modifies the errno variable. Changed all references to sem_post in the OS to nxsem_post().
sched/semaphore: Add nxsem_destroy() which is identical to sem_destroy() except that it never modifies the errno variable. Changed all references to sem_destroy() in the OS to nxsem_destroy().
libc/semaphore and sched/semaphore: Add nxsem_getprotocol() and nxsem_setprotocola which are identical to sem_getprotocol() and set_setprotocol() except that they never modifies the errno variable. Changed all references to sem_setprotocol in the OS to nxsem_setprotocol(). sem_getprotocol() was not used in the OS
libc/semaphore: Add nxsem_getvalue() which is identical to sem_getvalue() except that it never modifies the errno variable. Changed all references to sem_getvalue in the OS to nxsem_getvalue().
sched/semaphore: Rename all internal private functions from sem_xyz to nxsem_xyz. The sem_ prefix is (will be) reserved only for the application semaphore interfaces.
libc/semaphore: Add nxsem_init() which is identical to sem_init() except that it never modifies the errno variable. Changed all references to sem_init in the OS to nxsem_init().
sched/semaphore: Rename sem_tickwait() to nxsem_tickwait() so that it is clear this is an internal OS function.
sched/semaphoate: Rename sem_reset() to nxsem_reset() so that it is clear this is an internal OS function.
