From: Fabio Estevam <fabio.estevam@xxxxxxxxxxxxx>
Currently it is not possible to use 'mmc-pwrseq-simple' property with
this driver because mmc_pwrseq_alloc() is never called.
Call mmc_pwrseq_alloc so that we enable the support for providing a
reset GPIO to the Wifi/BT chipset.
Tested on a imx6sl-warp board:
root@imx6sl-warp:~# hciattach /dev/ttymxc1 3wire
Device setup complete
root@imx6sl-warp:~# hciconfig hci0 up
root@imx6sl-warp:~# hciconfig
hci0: Type: BR/EDR Bus: UART
BD Address: 2A:23:AA:6E:C7:A0 ACL MTU: 1021:8 SCO MTU: 64:1
UP RUNNING
RX bytes:795 acl:0 sco:0 events:29 errors:0
TX bytes:613 acl:0 sco:0 commands:29 errors:0

Changes since v1:
- Calling mmc_of_parse() breaks some boards due to bad card detect parsing.
Call only mmc_pwrseq_alloc() instead, which what we really need.
