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")

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

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.
