The target may have already configured its clock to run at a higher frequency and would have set SCKDIV and other dividers at that time. Don't restore the SCKDIV to its default or the flash interface may run too fast and programming will fail.
Otherwise, the default value is fine and there is no need to write SCKDIV.
If the working area is large enough, every fespi_write() results in just
a single algorithm execution.

Since merge of #3149 OpenOCD start with an unresponsive SAMD or SAM4L
resulted in segfaults. First was in cortex_m_assert_reset
(fixed by #3552), second was in samd_handle_reset_deassert()
/sam4l_handle_reset_deassert().
The change replaces mem_ap_write_u32/8 by target_write_u32/8.
It also takes better care about examining and polling target before
debug control registers are set. It prevents lockup when 'reset halt'
is issued on unresponsive cpu.

The MDR parts have two kinds of memory: main (regular memory-mapped
memory for code and data) and "info" (not memory-mapped). When OpenOCD
is requested to erase the info memory block, it should do just that,
instead of erasing everything including main memory.

To speed up downloads, OpenOCD sends gdb OK when a write is received,
even before the write has actually occurred. The failure is then
returned for the next write. That leads to the following confusing
behavior:
```
(gdb) p/x *((int*)0xdeadbeef)=8675309
$2 = 0x845fed
(gdb) p/x *((int*)0x80000000)=6874742
Cannot access memory at address 0x80000000
```
While it's actually the first write that failed.
This change hacks around this problem by not sending OK for small writes
(len<8) until the write has actually occurred. This does not impact
download speed, since during downloads (almost) all writes will have
much larger length.

struct flash_driver has a default_padded_value field that is similar,
but it can be changed by the user for the specific purpose of padding.
Add a new erased_value field and initialize it for all targets,
particularly stm32lx, xmc4xxx and virtual.
Use this value in core.c:default_flash_mem_blank_check(), the slow path.
Extend the target API to pass erased_value down to target code.
Adding an argument ensures that we catch all callers.
This allows us to merge xmc4xxx.c:xmc4xxx_blank_check_memory() into
armv7m:armv7m_blank_check_memory().
It further allows us to use default_flash_blank_check() in place of
xmc4xxx.c:xmc4xxx_flash_blank_check(), adding a potential slow path
fallback, as well as stm32lx:stm32lx_erase_check(), adding the potential
armv7m fast path with fallback to default_flash_mem_blank_check().
Fix a mips32 code comment while at it (zeroed -> erased).
The armv4_5 and mips32 target implementations will now error out if an
erase value other than 0xff is used, causing default_flash_blank_check()
to fall back to the default_flank_mem_blank_check() slow path.
