stop sched scan isn't an immediate operation
and we need to wait for PERIODIC_SCAN_COMPLETE_EVENT_ID
after sending a stop before changing internal state
and notifying upper layers.
Not doing this caused problems when canceling an existing sched
scan and immediately requesting to start a new one
with a different configuration as the FW was still
in the middle of the previous sched scan.

The chunk size used during firmware upload was set to 512, which is
the size of a single SDIO block (or two). This is very inneficient
because we send one or two blocks only per SDIO transaction and don't
get the full benefits of sdio block transfers.
This patch increases the chunk size to 16K. This more than doubles
the transfer speed both in wl127x and wl128x chips, with greater
impact on the latter:
wl127x: 512 bytes chunk -> ~132ms
16384 bytes chunk -> ~57ms
wl128x: 512 bytes chunk -> ~216ms
16384 bytes chunk -> ~37ms
Signed-off-by: Luciano Coelho <coelho@ti.com>
The sdio driver uses a block size of 512 bytes by default. With our
card, this doesn't work correctly because it sets the block size FBR
in the chip too early (ie. before the chip is powered on). Thus, if
we don't set it explicitly, block mode remains disabled in the chip.
If we try to send more data than fits in one block, the sdio driver
will split it into separate blocks before sending to the chip. This
causes problems because the chip is not expecting multiple blocks.
At the moment this is not a problem, because we use chunks of 512
bytes for firmware upload and the data is always sent in byte mode.
In the next patch, we will change the chunk size to a bigger value, so
this patch is a preparation for that.
