LemonBoy 705462d321 Correct calculation of the erase sector size 
The specification states that the real value is obtained by increasing
by one the value extracted from the csd register.

Make the initialization sequence more flexible

LemonBoy 52f5e0d41a Make the initialization sequence more flexible 
According to the SD specification v2.00 we this is the right way to
initialize a card using the v1 protocol in a forward-compatible way.

deepikabhavnani 1a02b0528c Fixed SD card intialization failure 
Few SD cards were failing for CMD41 as device was not ready after CMD55.
Added busy delay loop to make sure device is ready and than proceed.

Deepika 497aaaf915 SPI block read fix 
Using fix from mbed-os core, where few devices were failing with
SPI block read, as default data on SPI was sent 0x00.
Using API 'set_default_write_value' to set the default tx fill data.

Deepika cdbbea6c52 Fix: SD read failed for Strontium Card 
CMD9 fails for few cards if spi.write is performed during deslect of card
 Card immediately sends start packet token, which goes missing in this dummy
 write to SPI. Should not clock SPI bus in deselect operation.
