My intention was to release this code under GPL v2 license. For some
reason my initial commit 0fc6a323e1 ("spi: bcm53xx: driver for SPI
controller on Broadcom bcma SoC") totally missed licensing info.
MODULE_LICENSE was later added by Axel specifying "GNU Public License
v2 or later".
This patch clarifies situation by adding a proper header (with Copyright
line) and adjusting MODULE_LICENSE. It should be acked by every driver
contributor.

Setting of_node of master's dev seems to be a common way of letting it
work nicely with DT. This allows specifying device there instead of
hardcoding one in the driver code.
This was successfully tested with commit 1b47b98acc ("ARM: BCM5301X:
Add DT entry for SPI controller and NOR flash")

This implements more efficient reads of SPI-attached flash content.

Remove use of spi_unregister_master in remove function as
devm_spi_register_master in probe function automatically
handles it. To be compatible with the change, use direct
return instead of goto and remove unnedded label out.
Also, remove bcm53xxspi_bcma_remove as it is now redundant.

Use the normal {} instead of a macro to terminate an array.
Remove the macro too.

Converting milliseconds to jiffies by "val * HZ / 1000" is technically
ok but msecs_to_jiffies(val) is the cleaner solution and handles all
corner cases correctly.
This is only an API consolidation and should make things more readable

Mainly to fix missing MODULE_LICENSE.
Also add MODULE_DESCRIPTION and MODULE_AUTHOR.

Broadcom 53xx ARM SoCs use bcma bus that contains various cores (AKA
devices). If board has a serial flash, it's connected over SPI and the
bcma bus includes a SPI controller. Example log from such a board:
bus0: Found chip with id 53010, rev 0x00 and package 0x02
(...)
bus0: Core 18 found: SPI flash controller (manuf 0x4BF, id 0x50A, rev 0x01, class 0x0)
This patch adds a bcma driver for SPI core, it registers SPI master
controller and "bcm53xxspiflash" SPI device.
